Re: [Chimera-users] Chimera-users Digest, Vol 122, Issue 25

Hi Francesco, I doubt that modeller knows how to take into account inter-subunit information. I would be surprised if it does. As far as I know, it's a sequence-homology based model building module which also uses fold recognition and probably other pieces of information but not about oligomeric arrangement. When I dealt with a similar problem (modelling a dimer) I modelled the subunit and then superimposed each of the two subunits on top of the corresponding subunit of the known dimer, followed by Chimera's matchmaker. The resulting dimer is still considered a hypothetical structure by me.

The default is modeling each chain, one at a time. The chains are identical in sequence but the X-ray structure shows different localized conformations. Question: is modeller modeling by taking the other two chains into account? If already answered, beg pardon. thanks francesco pietra
