Re: [ccp4bb] scalepackvirus rejections and Rrin

Yarrow, as far as I know, scalepack, scalepackvirus and the other variants only differ by their respective array sizes (Someone from Wladek's or ZO's lab may be more suitable to comment on this). The rejections in the log file are controlled by the parameters 'write rejection file xxx' and 'rejec

Staurosporine come to mind as a general kinase inhibitor. I also second Artem's suggestion that ligands make a big difference, we had several cases of kinases which required ligands for crystallization success. Also make sure you eliminate any floppy ends which may interfere with packing. Good

Wenhe, Bioedit (http://www.mbio.ncsu.edu/bioedit/bioedit.html) is able to do this. You can also export a nice alignment as RTF file into Word from the graphics view. This comes in handy for publication and presentation. Cheers, Carsten From: CCP4 bulletin board [ma

John, You can use APBS in conjunction with PDB2PQR and PROPKA (all available from the ABPS website) for the calculations and Pymol for visualization. Good luck Carsten -Original Message- From: CCP4 bulletin board [mailto:CCP4BB@JISCMAIL.AC.UK] On Behalf Of john peter Sent: Friday, Augus

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 Allen, MR with low homology search models is also sensitive to the quality of your dataset. Besides the other recommendations already offered make sure that your dataset is of high quality. I recommend collecting a couple of good natives and try them all in your search. Good luck

Tarun, in my group we used to have a Proteum6000 CCD from Bruker. With the right detector descriptions from the HKL folks we able to use HKL2000, talk to the hkl folks, you may also need another license covering that detector though. Alternatively Bruker provides the Proteum suite (I think that

Hi Francois, instead of addressing the problem from the PDB side, you could take a look at the "embed" feature in Pymol. It allows embedding structural information into a special command script. It ties you down to PyMol, but on the other hand you don't need to worry about extending the PDB for
