With respect to protein folding, I want to fold a 42 amino acid loop (part
of a protein domain with known structure) which has no homologous
counterpart in PDB. Ab initio servers fail to assign a compact tertiary
structure to the loop, so I would like to see how MD tools can cope with
this problem. I 'm wondering if there is any way to keep the rest of the
protein rigid while running the simulation, cause the loop interacts with
the protein surface at many points.Is simulated annealing the right
approach? I'd appreciate any advice as I think the time scale of the problem
I described is accessible to MD.
thanks in advance,
