非結晶学的対称性 (NCS) | NCS oper: (Code: given Matrix: (-0.88, -0.48, 0.02), 詳細 | THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT OF INSULIN CONSISTS OF TWO INSULIN MOLECULES EACH CONSISTING OF TWO CHAINS. THIS ENTRY PRESENTS COORDINATES FOR MOLECULES I (CHAIN INDICATORS A AND B) AND II (CHAIN INDICATORS C AND D). THE QUASI-TWO-FOLD AXIS THAT TRANSFORMS MOLECULE I INTO MOLECULE II IS GIVEN IN THE MTRIX RECORDS BELOW. APPLYING THE THREE-FOLD CRYSTALLOGRAPHIC AXIS YIELDS A HEXAMER AROUND THE AXIS. THERE ARE TWO ZINC IONS SITUATED ON THIS THREE-FOLD AXIS. COORDINATES FOR THE ZINC IONS AND SOME WATER MOLECULES ARE INCLUDED BELOW WITH A BLANK CHAIN INDICATOR. | |
