Re: [ccp4bb] .phs file conversion
Bram, If you use the beta-test autotracing SHELXE, the .pdb file containing the poly-Ala trace also contains the space group. You presumably meant that the space group is missing from the SHELXL and SHELXD .pdb files, but of course you can read the .res files into Coot. George Prof. George M. Sheldrick FRS Dept.

[ccp4bb] XDS Viewer
Hi, I very recently downloaded and installed the Mac OS X executable of the new XDS Viewer program to inspect diffraction images. I have moved the program to /Applications. It starts up fine, but when I try to load an image it complains: Cannot open file! For image formats other than .cbf you need to install the 2cbf script. Please make sure you have added it to the executable path. Now 2cbf is in /usr/local/bin, which is in my path. I use /bin/tcsh as shell. Is there some confusion between the shell used by XDS Viewer (if any) and my preferred shell? Looking in the XDS Viewer.app directory I can't find any obvious clues.

Re: [ccp4bb] Eukaryotic Membrane Proteins
Hi there, The human protein FLAP from the MAPEG family was expressed in E. coli and also the K-channel, KirBac1.3 (although this is a chimera of mouse and B. xenovorans). The pubmed id codes for related papers are: 17703190 and 17600184 and the pdb codes for the structures are: 2QKS and 2Q7M. Hope this helps.

Re: [ccp4bb] Eukaryotic Membrane Proteins
Hi Raji- A number of GPCRs have been overexpressed in E. coli. Examples are Reinhard Grishammer's work with neurotensin receptor and Christopher Tate's work with B2-adrenergic and adenosine 2a receptors. The problem was not necessarily expression but proper outer membrane targeting of *active* receptors. This seems to have been overcome for the most part by the use of either helpful lipid additives like cholesterol analogs or by brute-force mutagenesis to find more stable and active receptors. However, I don't know of any crystals or structures from any GPCR system generated from bacteria. Hope this helps...

Re: [ccp4bb] Problem with setting up ccp4 gui
I had the same problem. In my case I think it was related to the part of ccp4 configuration that redefines python path. For some reasons (it breaks wxPython, at least in Hardy), I had it commented out and then after starting ccp4i I got these dbccp4i warnings. When I turned python part of ccp4 configuration script back on I got the same messages as Jan does - ccp4i window opens and then closes. What solved the problem for me was to delete the whole .CCP4 folder (it may be enough just to get rid of unix subfolder). Since it was fresh Hardy installation on a new machine, I didn't lose anything. HTH, Ed.

Re: [ccp4bb] XDS Viewer
Hi, Once you have a 2cbf in /usr/local/bin and start XDS Viewer from a terminal (/Applications/XDS-Viewer.app/Contents/MacOS/XDS-Viewer) it seems to work fine. However for the diffraction image viewing I would suggest adxv. You can find it at: http://www.scripps.edu/~arvai/adxv.html.

Re: [ccp4bb] XDS Viewer
Hi Andrzej, Thanks for the tip. It just seemed to me that since the package installed as a typical Mac OS X clickable program, then it was meant to run that way. Thanks also for info about adxv. I wasn't aware that there was a Mac executable for this program. Kay, the image I was trying to read was a .mar2560 file frpm the mar555 flat panel detector, which I had previously processed using XDS.
