Re: [ccp4bb] off topic: rmsf in simulation

2012-12-09 Thread Chandra Verma
to complement the very nice description by jeremy, you may wish to try and decompose the vibrational modes to get this sense by focussing on the origins of the "red shift" in the vibrational spectrum and this accounts largely for the increased vibrational entropies upon complexation. This

Re: [ccp4bb] How to compare the binding affinity between two domains structurally?

2009-10-26 Thread Chandra Verma
if the link between the domains is not part of the interface then perhaps a good first approximation may be to "cut" the linker and then use a program such as APBS to compute the binding energy.. > Hi, > > Recently we determined two structures of the same protein in complex with > different molec

[ccp4bb] question

2009-08-05 Thread Chandra Verma
Dear all Can anyone suggest examples where the same peptide is bound to the same receptor site in two or more different (very different) conformations and this binding has been resolved crystallographically as well as using ITC. In the extreme cases this could be two different proteins as well

An extension of this topic: does anyone know of examples where for complexes between the two proteins A and B, protein A has two different conformations at its interface? thanks chandra -Original Message- From: CCP4 bulletin board [mailto:ccp...@jiscmail.ac.uk] On Behalf Of Aaron O
