Dear All,
I’m currently refining the structure (2.0 A) with a cofactor PLP.
The PLP density is clearly indicates lysine residue is covalently
bound with PLP cofactor. But I don’t know how to link the cofactor
and lysine residue for further refinement. Any suggestions on how to
create the link between the PLP and lysine residue and do the
refinement with refmac would be greatly appreciated!
Thanks
Sincerely,
