In both molecules (A and B) there is a salt bridge between the C-terminus and the Arg1 side chain. The Arg5 side chain in molecule A is modeled in two conformations. The Val21 and Tyr27 side chains in both molecules are modeled in double conformation. His25 has different protonation and conformation in the two molecules. The zinc and sulfate ions lie on a common two fold axis. One MPD and two glycerol molecules are modeled in the solvent region. Blocked full-matix least-squares calculations were performed at the conclusion of the refinement.

Two of them (molecules A and B) constitute the contents of the asymmetric unit. The full coordination sphere is generated by the operation: -X, -Y, Z, of a two-fold axis. The zinc cation has a special position (occupancy 0.5) on this two-fold axis. ; _struct_biol.pdbx_parent_biol_id ? # loop_ _struct_conf.conf_type_id _struct_conf.id _struct_conf.pdbx_PDB_helix_id _struct_conf.beg_label_comp_id _struct_conf.beg_label_asym_id _struct_conf.beg_label_seq_id _struct_conf.pdbx_beg_PDB_ins_code _struct_conf.end_label_comp_id _struct_conf.end_label_asym_id _struct_conf.end_label_seq_id _struct_conf.pdbx_end_PDB_ins_code _struct_conf.beg_auth_comp_id _struct_conf.beg_auth_asym_id _struct_conf.beg_auth_seq_id _struct_conf.end_auth_comp_id _struct_conf.end_auth_asym_id _struct_conf.end_auth_seq_id _struct_conf.pdbx_PDB_helix_class _struct_conf.details _struct_conf.pdbx_PDB_helix_length HELX_P HELX_P1 1 LYS A 12 ?
