ENTRY REMARK 300 4INS PRESENTS COORDINATES FOR MOLECULES I (CHAIN REMARK 300 IDENTIFIERS *A* AND *B*) AND II (CHAIN IDENTIFIERS *C* AND REMARK 300 *D*). THE QUASI-TWO-FOLD AXIS THAT TRANSFORMS MOLECULE I REMARK 300 INTO MOLECULE II IS GIVEN IN THE *MTRIX* RECORDS. APPLYING REMARK 300 THE THREE-FOLD CRYSTALLOGRAPHIC AXIS YIELDS A HEXAMER REMARK 300 AROUND THE AXIS. THERE ARE TWO ZINC IONS SITUATED REMARK 300 ON THIS THREE-FOLD AXIS. COORDINATES FOR THE ZINC IONS AND REMARK 300 SOME WATER MOLECULES ARE INCLUDED WITH A BLANK CHAIN REMARK 300 IDENTIFIER. REMARK 350 REMARK 350 COORDINATES FOR A COMPLETE MULTIMER REPRESENTING THE KNOWN REMARK 350 BIOLOGICALLY SIGNIFICANT OLIGOMERIZATION STATE OF THE REMARK 350 MOLECULE CAN BE GENERATED BY APPLYING BIOMT TRANSFORMATIONS REMARK 350 GIVEN BELOW.
