Details | THE BIOLOGICALLY ACTIVE MOLECULE IS THE DIMER (MOLECULES A AND B OR C AND D). THE TWO DIMERS IN THE ASYMMETRIC UNIT ARE SITUATED IN SIMILAR CRYSTALLOGRAHIC ENVIRONMENTS. DURING REFINEMENT NON-CRYSTALLOGRAPHIC RESTRAINTS WERE APPLIED BETWEEN THE A AND C MOLECULES AND BETWEEN THE B AND D MOLECULES). NO NCS RESTRAINTS WERE APPLIED BETWEEN THE TWO MOLECULES OF THE DIMERS. DISORDERED SIDE CHAINS HAVE BEEN INCLUDED WITH OCCUPANCIES OF 0.01. RESIDUE CYS 60 IN THE B AND D MOLECULES APPEARS TO BE INVOLVED IN A DISULFIDE BRIDGE WITH 2-MERCAPTOETHANOL AS STATED FOR 1FRO.PDB. THE 2-MERCAPTOETHANOL HAS NOT BEEN MODELLED DUE TO THE LIMITED NUMBER OF DATA. |
