I have followed with interest the discussions regarding refinement of
proteins with ligands. I wonder if Pavel or anybody else could
comment on the refinement of proteins with covalently attached
ligands. I am currently handling that in CNS as I know how to write
the patches. Is this possible in phenix? Coudl it be handled by
generating a "new amino acid" like say a Cys with beta mercapto
ethanol attached and then get the program to link this "new amino
acid" via normal peptide bonds with the rest of the protein? What
about a capped N-terminus? can we make the "new amino acid" say N-
acetyl-Gly and get the program to put this at the N-terminus?
Any help is appreciated.
