I think the solution to your dilemma is rather straightforward: we introduce a Winter Standard Room Temperature (WSRT) and a Summer Standard Room Temperature (SSRT). This way, the folks from locales closer to the equator can always use SSRT, while those from more temperate climates can take advantage of using both WSRT and SSRT. The added benefit of this approach will be inclusion of researchers closer to either of the poles (which, forgive me for saying it, you so egregiously omitted from your considerations). Similar to the tropics, they could use just one standard - WSRT. Hope it helps your and so many young scientists' careers.

Obvious advantages would be less heating necessary for experiments at this standard temperature. Given that laboratories nowadays are not commonly heated to this high temperature anyway, it does appear to make sense. Members of tropical and subtropical countries have already expressed opposition to the proposal, because they have to reach room temperature by cooling rather than heating, so for them the proposal would mean more CO2 emissions, not less.

Re: [ccp4bb] Problems updating CCP4 via CCP4i
What is your operating system? I have encountered a problem on Scientific Linux 7 where ccp4um will not run correctly unless I clear out LD_LIBRARY_PATH first. This apparently happens because ccp4um requires certain libraries that ship with CCP4, and if the system libraries, which are a different version, appear in LD_LIBRARY_PATH ahead of the CCP4 libraries, trouble ensues. It is possible to put the CCP4 libraries at the start of LD_LIBRARY_PATH, but then that screws up every other program. csh/tcsh: unsetenv LD_LIBRARYPATH sh/bash: unset LD_LIBRARY_PATH === All Things Serve the Beam === David J.

Re: [ccp4bb] Fragile Crystals
There are multiple avenues you could explore. If you think handling is an issue, you could look into growing and collecting with "in situ" plates. You could test for diffraction at room temp, or even get a full data set at room temp by combining data from multiple crystals. If diffraction is not good at room temp, it is probably not going to be better under cryo conditions. As for cryo, instead of trying cryoprotectant A or cryoprotectant B, you could try a mixture of multiple cryoprotectants: https://pubs.acs.org/doi/abs/10.1021/acs.cgd.5b01692 Use of Multiple Cryoprotectants to Improve Diffraction Quality from Protein Crystals Senda, et al. https://doi.org/10.1021/acs.cgd.5b01692 Evidence of Kinetic Cooperativity in Dimeric Ketopantoate Reductase from Staphylococcus aureus JE Sanchez, PG Gross, RW Goetze, RM Walsh Jr, WB Peeples, ZA Wood Biochemistry 54 (21), 3360-3369 === All Things Serve the Beam === David J.

I am a PhD student working on a crystallography project to wrap up my dissertation research. I have purified a complex of two proteins, and I can consistently grow crystals in 10% PEG3350, 0.2M KSCN, 0.1M BIS-TRIS propane pH 7.5. These crystals have sharp edges and can grow to a large size (greater than 0.5 mm), but the crystals seem to be very fragile. When we open the drops to harvest the crystals, we have little time to harvest the crystals before they crack. When we move the crystals to a cryoprotectant, over time they start fracturing. We've tried using different percentages of glycerol, ethylene glycol, PEG400, and oil for cryoprotectants with no success. Needless to say, the crystals do not diffract well, with spot patterns that look very streaky/mosaic, which I presume is due to the defects that we see in harvesting/handling. We have screened for alternate crystallization conditions, but we seem to get the same morphology in other conditions. Does anyone have suggestions for additives we could use post-crystallization to help stabilize our crystals? Thanks for your advice!

Re: [ccp4bb] Dry shipper in limbo
FedEx missing deadlines on "overnight" shipments is not uncommon, I advise everyone to ship dewars to arrive at least one extra day in advance. Also, their online tracking page could be better. They show the original expected delivery time even if the shipment has already missed an intermediate transfer point. The delivery time does not get updated until the original delivery time has been passed. The multiple lost days and the international complication are unusual details and I don't have any specific advice on that. === All Things Serve the Beam === David J.

This involved gaining access to the FedEx center and talking to the right people. I would absolutely not wait this out because your shipment is probably somewhere in the corner of a distribution center used as a seat by employees taking a break. I can attest to the fact that they do have such corners where “problematic" shipments are piled up! Despite what you were told on the phone or could deduce from any online tracking systems (in our case the dry-shipper was not even trackable), there is still a (very good) chance that your shipment might still be at a regional collection/distribution center. The key is to get to any information about where this place might be, talk to the local people, and find out what the actual route of the shipment might have been after getting picked up from your lab. The routes often involve intermediate collection/distribution sites. To their credit, and in contrast to the general FedEx customer service, the people at the regional FedEx distribution center (including the shift manager) were very empathic and helpful, and used means that go above and beyond SOPs to help. This included sharing photos of the shipment via WhatsApp with drivers/employees of the three previous shifts etc… Despite the volumes of work they handle, drivers and other courier employees actually do remember unusually looking shipments, such as a shipping-case containing a dry-shipper!

It has only recently been possible to extend protein structure prediction to two hundred million cataloged proteins. Characterizing the structures of the exponentially growing billions of protein sequences revealed by large scale gene sequencing experiments would necessitate a breakthrough in the speed of folding. Here we show that direct inference of structure from primary sequence using a large language model enables an order of magnitude speed-up in high resolution structure prediction. Leveraging the insight that language models learn evolutionary patterns across millions of sequences, we train models up to 15B parameters, the largest language model of proteins to date. As the language models are scaled they learn information that enables prediction of the three-dimensional structure of a protein at the resolution of individual atoms. This results in prediction that is up to 60x faster than state-of-the-art while maintaining resolution and accuracy. Building on this, we present the ESM Metagenomic Atlas. This is the first large-scale structural characterization of metagenomic proteins, with more than 617 million structures. The atlas reveals more than 225 million high confidence predictions, including millions whose structures are novel in comparison with experimentally determined structures, giving an unprecedented view into the vast breadth and diversity of the structures of some of the least understood proteins on earth.

You could look for the most likely canadidata based on multiple sequence alignments. Refinement of both alternatives can give hints in B-factors and if you are lucky in difference density. But if hydrogen bonding gives no hints, then the residues are also not in a place where the identity really matters. You can give your best guess with a CAVEAT record or use the name UNK to indicate that you do not know what the residue is. You would loose the knowledge that it is either VAL or THR in that case.

Re: [ccp4bb] ligand binds to one molecule
I think it would be a mistake to generalize. I have seen a situation in which 1 of 4 sites was occupied, the ligand was not included in the crystallization solution(which means it must have been bound beforehand) and the site participated in crystal contacts. I do not doubt that examples of the opposite causality exist. And the data I used to make my conclusions in my own example came from outside the structure itself. === All Things Serve the Beam === David J.

What it doesn't answer is a chicken or the egg question: do the different environments in the crystal allow or force different conformations (e.g. open or closed loops) and/or different (active) site occupancies or do different states in an oligomer allow or force crystallization only in a packing and space group with multiple states? Latter could be due to an anti-cooperative binding to a dimer. We have seen this in the dimeric Tet repressor: wt binds the ligand (a tetracycline) in each monomer of the dimer with one chain in the asymmetric unit, but some of the mutants bind only one ligand per dimer (confirmed by ITC, Biochimica et Biophysica Acta, 2020).

Re: [ccp4bb] RAID array
I agree about the complexity of the RAID situation. But it can be narrowed down a bit. Since the claim is made there were only two hard drives, the only possibilities are: RAID 0 - "striping". In which case his data will probably not be recoverable, and he would be unable to boot. RAID 1 - "mirroring". In which case the data may be recoverable. This is probably the case, since from the description the machine is booting but the login process is unsuccessful. If the RAID is set up with hardware, there may be entry into the controller from the BIOS boot process. If the RAID is set up in Linux software, then you need to get logged in somehow with root privileges. Details may vary a bit depending on which Linux distribution is involved (which was not mentioned). You could try to boot into "rescue mode" from the Linux installation media (DVD or USB stick, usually). Or you could try to boot into "single user mode" by altering the boot command during the boot procedure (details will vary with distribution). Or you could try setting to boot up in nongraphical mode. Like I say, this varies with Linux distribution so I won't try to give a line by line set of instructions. My experience is all with Fedor and Scientific Linux. Once you are in, you need to assess the situation. If RAID is set up with software, there will be a configuration file, typically /etc/mdadm.conf, and a status file, typically /proc/mdstat. You can look for these files for clues to how the RAID is set up, and what its status is. You would need to figure out how your existing drive is configured by checking out the partition arrangement with /usr/sbin/fdisk or /usr/sbin/parted. Then you would need to set up partitions on the brand new drive in the same way. Once the partitions exist, you would try to add the partitions into the RAID volume with /usr/sbin/mdadm. You are going to need to read the man pages for mdadm and probably search for help online. Once the RAID set is successfully reconfigured, it would take probably a few hours to copy the data from the good device to the new one.

These details influence what the user will notice when a disk goes bad. Without knowing what you have, it is difficult to help. As an example, by default in my lab we have the operating system on mdadm RAID1 which consists of two disks that mirror each other. If one of the disks fails, typically we only notice this when inspecting the system log files. Replacing the disk, and re-silvering the RAID1 is not trivial and requires some reading of material on the web.

Re: [ccp4bb] [COOT] 120hz LCDs and coot stereo
My current understanding is that 1) The new 120Hz LCD monitors are not compatible with the old goggles. Something about the type of polarization used for the shuttering effect. So if you were going to try out one of the new 120Hz monitors (~ $400) you might also want to spend on the nVidia glasses and emitter kit (~ $200) 2) The 120 Hz LCDs are not supported under Linux drivers by nVidia at present. Whether it might actually work or not, I can't say. I am encouraged by the mention that the nVidia emitter can accept a signal from the mini-DIN stereo port on some Quadro cards. http://www.nvidia.com/object/quadro_pro_graphics_boards.html 3) As someone mentioned already, the Zalman LCD monitors, which are not 120Hz and do not require goggles, but have diminished resolution, are currently supported.

However, it is worth noting that PC users can access stereo 3D (via 3D Vision IR emitter glasses) with a $139 Quadro 300-series card whereas Mac users must spend 12X more for an ultra high-end 4000-series card (which will only work IF they happen to own a compatible Mac Pro model).

Hopelly that will change in a matter of weeks, however, they will likely require a quadro card, 3D vision emitter, and an appropriate driver from nVidia. Mac support for 120 Hz seems unlikely unless nVidia and Apple deliberately get together to create a joint solution. Due to proprietary aspects of each component (Mac OpenGL drivers, nVidia emitters), this isn't something either Apple or nVidia could accomplish alone. Zalman LCDs can do stereo 3D (with reduced vertical resolution) but they require software modifications or a Quadro card with the updated windows or linux driver

Re: [ccp4bb] protein folds
Concerning the number of proteins folds in existence vs. the number of folds already identified: Ed Berry had some good points regarding sample statistics, and I assume the mathematics of that sort of thing is formalized somewhere. The number of examples per protein fold will be skewed by the common use of molecular replacement for phasing and the tendency of researchers working in one field to solve several related structures. Keep in mind also the mechanism through which new folds have evolved; i.e. through the generation of new genes via duplication, insertion, deletions, point mutations, and the occasional frame shift.

The machine lived up to some of the recommendations I saw on this board. However, there is this annoying problem with air bubbles entering columns and I cannot figure out the source. The system would be free of any air bubbles in the beginning, and performs fine when water is loaded using needle/syringe into the 5ml superloop and then injected into the column. When protein samples are injected the same way, a lot of air bubbles would appear and get trapped inside the ion exchange column, leaving yellowish marks on the Uno columns and eventually reducing their performance. I've been a FLC/AKTA user for about ten years and have never seen such problems. I doubt it is due to a faulty injection valve because we recently had it replaced for other reasons. We did move a backpressure generator (a little black piece) from post-column position to before-column, otherwise we cannot run sizing columns in a reasonable flow rate. I'd like to hear if you have similar experiences and how you fixed the problem. Thanks a lot! Ailong --

Re: [ccp4bb] Merging CCP4i projects from two computers
Unison is good, as is rsync, but in this particular case will be complicated (if ( understand correctly) by the use of the identical file names for different files on the two computers. I don't see an easy, automatic way around this. I would rename one or some of the directories, put them on the same computer, and then manually go through them and decide which ones are duplicates, and which are unique but identically named files, and rename those. If this is a Unix/Linux system, it might be useful to know that the diff command can work on an entire directory, if you plead with it sincerely enough and use the right parameters. In future, unison or rsync could be used on a regular basis to avoid another situation like this arising. Back in the good old days, we were able to share disks between computers with something called NFS, and even further back, file versioning in VMS might have been relevant and useful.

Re: [ccp4bb] Unknown density
Remember that since it is on a special position (2-fold?), you may not be looking at a single object, but an overlay from two or more positions. The anomalous map is very useful; the mystery molecule must have an anomalous scatterer. It would be even more helpful if you had mentioned the wavelength of the data. Anyway, the only thing in the list of mother liquor ingredients you provided that scatters anomalously is calcium, which fits in with the Asp ligands. The additional ligands for the calcium might be water or acetate. So: my guess would be two positions of Ca2+, one right on the axis and one off the axis (and doubled by the symmetry). You can try placing Ca atoms at these positions and see what the occupancies and thermal factors refine to. For example, start with an occupancy of 0.5 at each position and see if the thermal factors refine to a value comparable to nearby protein atoms.

Re: [ccp4bb] Cocrystals - should they pop up under native conditions?
Don't call them co-crystals until you've actually shot them and seen the density. It will depend not only on the ligand but on the ligor(?) as well. You don't mention the identity of your ligand or ligor(?). You mention that some of your screens are under oil, so I will point out that some non-polar ligands might prefer to partition in the oil rather than the mother liquor. That would explain why the crystals look so much like the native. Posting to the BB is always a valuable way to fill time until you can collect the data which will answer the question.

Can I just anistropically refine the mercuries while I keep the rest isotropic? Yes, that sounds worth a try. At 2.2 A you probably don't have the data/parameter ratio to justify anisotropic refinement for the whole molecule, but since you know the mercury atoms are not being treated adequately, adding an extra ~ 10 parameters to refine them as anisotropic is worth a try.

Another way to reduce air scatter would be to reduce the air by putting the experiment in a helium box. -- === With the single exception of Cornell, there is not a college in the United States where truth has ever been a welcome guest - R.G.

Re: [ccp4bb] X-ray generator uninterruptible power supply

What I did get was a UPS for my cryostream - I figured that the data collection can always be restarted if the generator died in the middle of the night, but once the crystal is gone, it's gone. I paid less than $10k for a UPS that can run my Cryojet for over 15 hours, so even if the power goes out in the middle of the night, I can come in and rescue the crystal the next day. That's a good idea, we do that now on our crystallography beamlines. -- === With the single exception of Cornell, there is not a college in the United States where truth has ever been a welcome guest - R.G.
