REMARK 300 REMARK: THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT OF INSULIN CONSISTS OF REMARK 300 TWO INSULIN MOLECULES EACH CONSISTING OF TWO CHAINS. THIS REMARK 300 ENTRY PRESENTS COORDINATES FOR MOLECULES I (CHAIN REMARK 300 INDICATORS *A* AND *B*) AND II (CHAIN INDICATORS *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 BELOW. REMARK 300 APPLYING THE THREE-FOLD CRYSTALLOGRAPHIC AXIS YIELDS A REMARK 300 HEXAMER 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 BELOW WITH A BLANK CHAIN REMARK 300 INDICATOR. 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.
