Re: [ccp4bb] Dry shipper in limbo
Dear all, Just a note as we have been experimenting with this lately after some lost shipments. We went with Lightbug pro and are ordering more of those. https://lightbug.io/product/pro/ One can customize it to send updates only when moving out of the premises or geofence to significantly lower the costs of updates and there is an API one can use for integration. It is also not limited to Apple ecosystem as we do not need to have an iDevice to connect to it and there does not need to be an iPhone in the storage facility where the lost dewar is. We aim to add a dewar management and tracking system to the IceBear we use to track crystallization, crystals and data (this feature not yet available) and that is also why these features are rather important for us. https://icebear.fi/ This is just one possibility but based on the testing we have been happy with this solution. And of course, since we started using it, the couriers have not lost any dry shippers.

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!

Hi, Slightly deviating from the original thread perhaps: I am having trouble with recent releases of Ubuntu on my Toshiba Satellite laptop, mainly associated with ACPI. The internet is awash with discussions on how to fix the problems with ACPI (fan speed, screen brightness etc). None of the solutions that have been suggested, work for me. I still run Ubuntu 8.04, which is ok, but all versions after that effectively mean the screen brightness is stuck at one level and the fan either runs on full speed or not at all. Other people in the lab have reported similar problems with their laptop (various makes).

I am curious. What is the resolution of dataset? stephen Quoting Daniel Bonsor bon...@bbri.org: Hello again I currently have some unexplained density in my structure. As you can hopefully see from the images (see file), the density is dumbbell shaped. Whatever it is, it is coordinated by Asp and Glu residues. To me it looks like each lobe is a ring structure. The crystallization condition was: 6.5% PEG 8K, 10mM ZnSO4, 100mM sodium cacodylate pH 6.5, 100mM Am2SO4, 1% glycerol, with 20% glycerol as cryo. Protein was originally in 50mM Tris, 50mM NaCl pH 7.5. I originally placed a single Zn at the center of each lobe. Though after refmac, the Zn was displaced to one side. Two zincs in each dumbbell may have worked, but I am dubious about two zinc atoms being 4A apart and there is still some unexplained density. Are there any possible cyclization reactions of Tris, cacodylate or glycerol may have undergone to explain the density? Or is it simply a highly ordered water network? Or is there some other explanation?

Re: [ccp4bb] Buried surface area (BSA) vs. oligomeric interface
Hi, just a place I would perhaps start looking: http://www.ebi.ac.uk/msd-srv/prot_int/picite.html ~L~ __ Lari Lehtiö Pharmaceutical Sciences, Department of Biosciences Åbo Akademi University, BioCity, FIN-20520 Turku Finland +358 2 215 4270 http://www.users.abo.fi/llehtio/ __ Quoting Sollepura Yogesha yoge...@scripps.edu: Dear All, We found that our structure is having a large buried surface in its dimer interface (~18% as calculated by AREAIMOL). This dimer has not been observed in earlier studies and right now we have less data to support this strong interface formation. I am looking for some literature which provide guidelines to understand the relation of BSA or crystal contacts with oligomeric interfaces. Any suggestion is highly appreciated Thanks in advance Yogi
Re: [ccp4bb] Protein crystallizes while concentration
Dear Rajkumar, I would use dialysis buttons. E.g. http://hamptonresearch.com/product_detail.aspx?cid=10sid=63pid=111 Put your protein to the button and seal it with a piece of dialysis membrane. Place this to a linbro plate (easy to look with a microscope), fill the well with low salt buffer and seal with a cover slip. To make the diffusion slower, you can put the dialysis button inside a dialysis tubing with some high salt buffer and place this to a bigger volume of low salt buffer. ~L~ __ Lari Lehtiö Pharmacy, Department of Biochemistry and Pharmacy Åbo Akademi University, BioCity, FIN-20520 Turku Finland +358 2 215 4270 http://www.users.abo.fi/llehtio/ __ Quoting E rajakumar e_rajaku...@yahoo.com: Dear All I am Rajkumar, working on the protein which has unusual behavior while concentration. When I kept protein in 15 mM Tris 7.5, 150 mM NaCl and 5 mM DTT, the solubility of the protein is decreases drastically and tend to crystallize while concentration. Protein cannot be concentrated more than 3 mg/mL, however I noticed white turbid protein if I force to concentrate 3mg/mL. When I observed this white turbid solution under the microscope, I noticed shower of tiny protein crystals which are needle in shape. I screened freshly purified protein (2.5 mg/mL) in different Hampton and Qiagen screens, strangely none of the conditions gave the crystals. I concentrated left over protein at 15oC at 3 mg/mL and kept in the 4oC for 4 days again I noticed shower of crystals. This protein solubility is increased to ~20mg/mL when I kept in 15 Tris 7.5, 400 mM NaCl, 5% Glycerol and 5 mM DTT, but did not crystallize while concentration and also after screening with Hampton and Qiagen screens. My queries are 1. How do I get the crystals in the crystallization set up rather than while concentration, so that I can control the diffusion and finally nucleation? 2. Could anybody give me suggestions on seeding in this type of situation? 3. Any comments on reverse vapor diffusion for this type of protein are most welcome. So I can keep protein in high ionic strength (~400 mM NaCl)and diffuse against low Ionic strength or deionized water? Or any other protocol? Any suggestions are well appreciated.

Re: [ccp4bb] off topic: multiple structural sequence alignment
I ended up using multiprot and staccato recently http://bioinfo3d.cs.tau.ac.il/MultiProt/ There is a server for multiprot, but I downloaded the applications. I still ended up doing quite a bit manual editing in filling the gaps in the structures etc. I stumbled also over a link about the matter comparing different programs (by Dr Elaine Meng): http://www.cgl.ucsf.edu/home/meng/grpmt/structalign-content.html ~L~ __ Lari Lehtiö Pharmacy, Department of Biochemistry and Pharmacy Åbo Akademi University, BioCity, FIN-20520 Turku Finland +358 2 215 4270 http://www.users.abo.fi/llehtio/ __ Quoting Ronnie Berntsson r.bernts...@rug.nl: Dear all, A bit off the topic question perhaps. I am trying to find a program which can do multiple structural sequence alignments. What I would like is a program which can take as input PDB codes (or files), and which will output a multiple sequence alignment in FASTA format with the full sequences of the supplied proteins intact. Preferably said server/program should be able to handle at least 20 input pdbs at once. I've been looking around, but have so far failed to find a program which does this. If anyone knows of a program or server which could handle this, I would be very grateful. Cheers, Ronnie Berntsson
Re: [ccp4bb] anisotropic diffraction in refinement
There is a ellipsoidal truncation and scaling server you might want to try. http://www.doe-mbi.ucla.edu/~sawaya/anisoscale/ ~L~ __ Lari Lehtiö Pharmacy, Department of Biochemistry and Pharmacy Åbo Akademi University, BioCity, FIN-20520 Turku Finland +358 2 215 4270 __ Quoting Justin Hall hallj...@onid.orst.edu: Dear All; I am working with a data set which is anisotropic. The resolution limits are ~ 2.75 by 3.45 A. The I have integrated (using Mosflm) the data out to 2.75 A, the data therefore includes a mix of real (I/sig 1) and imaginary (I/sig ~1) data past the 3.45 A resolution bin. I am concerned that the presence of the poor quality data in the outer shells will cause my good data to 2.75 A resolution to be down weighted in refinement. Since anisotropic resolution limits do not seem to be an option, are there other tools that would allow proper weighting for this situation? Cheers~ ~Justin Hall Oregon State University

Hi, In a new structure we observed a hydrogen bond between an aspartate side chain and a main chain carbonyl group. Because both of them are electronegative, I am puzzled. My questions are: does this hydrogen bond make sense at all? any precedent for such a hydrogen bond? I would appreciate your help very much! Frank
