REMARK 3 THE THIOL GROUP OF CYS 2 IS DISORDERED IN MOLECULE 1 REMARK 3 (THE WHOLE OF RESIDUE 2 IS DISORDERED IN MOLECULE 2). REMARK 3 THE THIOL GROUPS OF CYS 16, CYS 88 AND CYS 130 ARE REMARK 3 OXIDIZED. CYS 16 A, CYS 88 A, AND CYS 16 B WERE REMARK 3 MODELED WITH TWO OXYGEN ATOMS COVALENTLY BOUND TO THE REMARK 3 SULFUR ATOM. CYS 130 A, CYS 88 B AND CYS 130 B WERE REMARK 3 MODELLED WITH ONLY ONE OXYGEN ATOM ATTACHED.
