Hello everyone!
I have run into a problem in a 55kD recombinant human protein crystallization
(expressed in E.Coil). The purity is pretty good. However, it behaves as high
oligomers in the buffer with 300mM NaCl and behaves as dimers with a little
high oligomers in the buffer with 2000mM (2M)
Carsten,
Phenix does do this a little differently and yes it ignores existing ligands
(which I like). CCP4 comes with is own library of existing ligand cif files
from the pdb which coot also uses. The best way is to try and find a unique
code to call your new ligand. That way you can have some
Hi Louise,
for internal use the name of your ligand does not matter as long as you have a
.cif file describing the restraints. I am not sure about the behavior of
refmac, but in phenix the presence of a defined name in a .cif file takes
precedence over any duplicate entry in your monomer librar
Hi All.
We have a Rigaku R-AXIS IV detector and controller which we would like to
donate to create some space at our core facility. The equipment should be in
good working order but hasn't been used in about 18 months. It is currently
located at the Beth Israel Deaconess Medical Center in Bosto
The "Best" column gives Wilson plot values obtained according to this

Garib kindly sorted out this problem and "external harmonic" works well
for ligands now.
He said that the next ccp4 update will include this version of refmac
(5.8.0070 or later).
Thanks again for your help.

Hi Louise,
You can go through the mon_lib_list.cif file of the CCP4 dictionary to get a
name that is free (e.g. A97). It would be nice is a certain name would be
reserved for this by the PDB. LIG was a good candidate, but it's gone just
like other nice options (XXX, ZZZ, 000).
Cheers,

Hello,
we have a structure with a novel ligand. I used to use LIG for new ligands but
now that is taken in the PDB by
3-PYRIDIN-4-YL-2,4-DIHYDRO-INDENO[1,2-.C.]PYRAZOLE. Any suggestions for a
generic name that is not already used?
thanks and best wishes,
Louise
Dear All,
Recently, I have used TRANCATE to process some data. There is a Wilson plot
table in its log file. The first column of table is resolution, the second
is ln(I/I_th). And the third column is named "Best". I want to know what
mean the "best". Is it the theoretical estimate of Wilson plot
