[ccp4bb] Problems with PDB validation

2012-11-12 Thread Krithika Sundaram
Hi all, I am currently validating my protein and experiencing a few issues. I am unable to fix the torsion angles for eight residues no matter what I try. There are 3 models deposited on the PDB website belonging to the same protein. Five of the residues’ torsion angles (of the eight) are cons

Hi all, Just wanted to ask if anyone has generated low resoultion density maps before? If yes, can anyone help me with this or point me in the right direction? Thanks in advance for your help!

[ccp4bb] Molecular replacement

2012-04-18 Thread Krithika Sundaram
Hi all, I am working on an oxidoreductase and having some trouble during molecular replacement. The resolution of the crystal is 1.7 A and the space group is I4122 (a = b = 121.086, c =156.93 and alpha = beta = gamma = 90). The cell content analysis results predicted two molecules in the
