There is no need to convert the phs to mtz if you just want to inspect 
the map from Shelxe.
You can read in the .phs file into Coot. Since the .phs file does not 
have unit cell dimensions, you also need to read in a pdb.
Unfortunately the pdb file written by  Shelxe does not contain the 
spacegroup, but fortunately the res file does, and Coot is able to read 
this file too.

So if you read in the .phs and the .res file, Bob's your uncle.

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.

[ccp4bb] XDS Viewer

2009-03-05 Thread Derek Logan

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.


Thanks
Derek

Re: [ccp4bb] Eukaryotic Membrane Proteins

2009-03-05 Thread Karen McLuskey

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.

Regards,

Karen

Re: [ccp4bb] Eukaryotic Membrane Proteins

2009-03-05 Thread Brad Bennett
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

2009-03-05 Thread Ed Pozharski
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.

 Subject: [ccp4bb] Problem with setting up ccp4 gui
 
 Hi all,
 I have been struggling with installing the new CCP4 package. I run
 RedHat Enterprise 4 and have previously used older packages with
 success. After I untar and run ./install as root everything seems to
 install just fine. When I run ccp4i -c to configure I think something
 goes wrong or extensions get misdirected. If I try to run all the
 scripts to test, they all seem to execute fine.
 I have had luck starting the GUI as root or user but when you get to the
 part where projekt directories are setup the GUI stops working and
 cannot be restarted (showing the message below)

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

2009-03-05 Thread Derek Logan

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.
