Dear Jane, If you rename one of domains with a different chain ID (in the PDB) you can submit the structure to PISA (http://www.ebi.ac.uk/msd-srv/prot_int/pistart.html) and it will do the job. Regards Rafa === Rafael Fernández Leiro Departamento de Biología

[ccp4bb] crystal contacts

2010-02-22 Thread amit sharma
Dear All, Apologies for a non-CCP4question. I have a structure of a dimeric molecule, where the interfaces between monomers is held by a couple of tyrosine residues (per monomer) juxtaposed with each other. The molecule exists as a dimer in solution. Are there ways/programs to show that the

Dear Amit As Paul suggests, you can get some idea if the interaction is consistent with biologically relevant protein-protein interfaces through looking at the the size of the interface and the nature of the contacts in the interface. There is substantial literature on this topic, see

I want to process bunch of frames with extremely short step - i.e. these are 0.5degree oscillations but crystal only rotates by 1 degree over 1000 frames (I would have kept it at the same orientation if Rigaku control software would allow zero step). Denzo can process the frames all right, but

Try grepping crystal your .x files (or whatever you called the denzo output files). Also grep for start. By default denzo updates start-phi to the end of the previous oscillation. Since 0,5 degree is within radius of convergence, it re-refines crystal rotx to be compatible with this assumption

[ccp4bb] Per-residue RMSD for multiple structures?

Hi all, I am comparing 4 very similar (1.5A rmsd) large (750 residues) structures, but struggling to find a way to generate a figure that conveys where they are most alike and where they diverge. Simply drawing a superimposed set of backbone traces results in what looks like colored

One possible representation is the sausage produced by MOLMOL. It is meant for NMR ensembles - the thickness of sausage is directly proportional to local RMSD. Take a look at this image: http://www.msg.ucsf.edu/local/programs/molmol/images/tutorial_ex3.gif MOLMOL can be downloaded from

I am pretty sure you can do this using LSQMAN from Gerard (BluRay?) Kleywegt. The pertinent commands are MCENTRAL to determine the 'most representative structure' (i.e. the one to align upon and show in the figure), MALIGN to do the alignment and then MPLOT to calculate a 'multi-RMSD' for each
