THE MODEL CONTAINED AT THAT POINT ALTERNATE REMARK 3 CONFORMATIONS, A CIS-PEPTIDE BOND (LEU78-LYS79), AND THE ACTIVE REMARK 3 SITE LIGANDS, ALL OF WHICH WERE PLACED IN UNAMBIGUOUS ELECTRON REMARK 3 DENSITY. REFINEMENT CONTINUED WITH SHELX-97, WITH REFINEMENT OF REMARK 3 ANISOTROPIC TEMPERATURE FACTORS. RIDING HYDROGEN ATOMS WERE REMARK 3 ADDED IN THE LATTER STAGES.
