Hello,
Is there a ccp4 tool to find automatically the smallest virtual
orthogonal box that contain a given PDB ?
Even if your favorite tool is not part of ccp4, I would be happy
to know about it. ;)
Thanks,
Francois.
As I recently learnt from Andy Arvai, the -nopixmap is not needed if
the (free) NX server has
AGENT_EXTRA_OPTIONS_X=-defer 0
in its node.conf .
I like this a lot because I tend to forget about the -nopixmap option,
_and_ it does not work for the zoom window.
HTH,
Kay

Hi,
I have a job opportunity for a highly motivated individual in the area
of structure-based ligand design design in my group.
Check out our University web page for more information about the job and
on how to apply

Strictly speaking even Tim's solution may not give the true 'smallest
box', by which I assume is meant 'minimal volume box'. I suspect
moleman does this calculation (my apologies to Gerard if I'm wrong!)
by determining the axes of inertia, then rotating the molecule by the
matrix of eigenvectors
There are three diastereomers, two of which I think work. The meso
compound, however supposedly does not freeze clear. Hampton sells two
of these in their kit, but doesn't specify the stereochemistry of one
of them.

I have a program that would calculate the limits of the protein along
it's axes of inertia (besides doing many other things).
If you are interested, please let me know.
Thanks

How do I convert the B-factors from my final structure to full B factors if I
did not use TLS refinement? I have been refining isotropic B-factors. Do I
switch to overall B-factor refinement, do something else, or have I missed the
point altogether?
It may be a dumb question but best to be
thanks so far for sharing your experience with Butanediol. But is it
important to use a specific enantiomer ? Are you all only using 2R3R-
Butanediol which is quite expensive ?

Dear Paul,
You can also use idiffdisp, which might do what you want.
See

Hi Daniel,
How do I convert the B-factors from my final structure to full B factors if I
did not use TLS refinement?
a non-ccp4 tool:
if you have PHENIX installed then:
1) if your PDB file has TLS matrices in its header and residual
B-factors in ATOM records, then:
phenix.tls model.pdb
Dear all,
I would like to know which is the more suitable method of using
2,3-Butanediol as cryoprotectant? Addition in to reservoir buffer or crystal
soaking or both can be tried?
Cheers

Hello,
Here is our lab's work with HEK293T in bioreactor:
Pak JE, Rini JM., X-ray crystal structure determination of mammalian
glycosyltransferases., Methods Enzymol. 2006;416:30-48.
Dear All;
I have a crystal structure collected on in house X-ray facility from
Bruker using Xprep. I submitted the paper but the reviewer ask for the R
merge. As I can't access to the computer at the moment its crashed out.
But I have the prp file which have the R init values. My question is!!!
And in the paid for version the keyword is
AgentExtraOptions = -defer 0
