Dear all,
I am refining a structure with a partially
occupied ligand. The binding site contains a
Glutamine residue with a dual conformation with
the ‘B’ conformation overlapping with the ligand.
I have named the ligand ‘ALIG’ but when refining,
Refmac notes a number of VDW deviations and the
ligand and side-chain are moved away from each
other and out of the density. When I refine
without VDW restraints the ligand and side-chain
refine well in the density but I would like to be
able to use these restraints for the rest of the
structure. Is it possible to have Refmac ignore
these restraints just for this ligand and residue?
Many thanks,
Alastair
