[ccp4bb] refmac5, SIGF/SIGIMEAN labels

2012-07-26 Thread Jan Abendroth
Hi all, we noticed a strange behaviour of refmac5.7.0029 that comes with CCP4-6.3. We run a most basic script: 5 rounds of restrained refinement with all default parameters. The input mtz file contains besides H/K/L and FreeR_flag, IMEAN/SIGIMEAN, and F/SIGF. Refmac 5.6.0117 outputs F/SIGF, whil

Hi Sebastiano, In this case, having your own dictionary for both residues together will be useful. Same dictionary will be used in refmac refinement too, if you need precise refined positions. It will be easier, if you do the editing in text file. Get the CIF files for Cys-X together, re

[ccp4bb] ADP binds to the protein in solution but not show up in the structure

2012-07-26 Thread Ni shi
Dear CCP4ers, We have crystallized a kinase without adding any nuceotide, and the structure does not show any eletron density at the ATP binding site. Yet most of the bacterial-purified proteins of this family and also the structures contains ADP . So we boiled the bacterial-purified protei

Thanks Manish. With the help of Paul and using JLigand, which is nicely connected to coot in version 0.7-pre1, I managed to create the bond and have the correct library CIF file. Still, I can't manage to "regularize" the bond and residues close to it. It looks like I have to go through refcmac
