非結晶学的対称性 (NCS) | NCS oper: (Code: given Matrix: (-0.105647, -0.993868, 0.03264), ベクター: 詳細 | THE ENZYME IS A DODECAMER COMPOSED OF SIX CATALYTIC CHAINS AND SIX REGULATORY CHAINS THAT CAN BE DISSOCIATED INTO SUBUNITS. THE ASYMMETRIC UNIT OF THE CRYSTAL CONSISTS OF ONE THIRD OF THE MOLECULE - TWO CATALYTIC AND TWO REGULATORY CHAINS. CHAINS *A* AND *C* (REFERRED TO AS C1 AND C6 RESPECTIVELY IN THE *JRNL* REFERENCE ABOVE) ARE THE CATALYTIC CHAINS CONSISTING OF 310 RESIDUES EACH. CHAINS *B* AND *D* (REFERRED TO AS R1 AND R6 RESPECTIVELY IN THE *JRNL* REFERENCE ABOVE) ARE THE REGULATORY CHAINS CONSISTING OF 153 RESIDUES EACH. THE NON-CRYSTALLOGRAPHIC TWO-FOLD AXIS, WHICH IS SPECIFIED ON THE *MTRIX* RECORDS BELOW, RELATES THE *A* AND *B* CHAINS TO THE *C* AND *D* CHAINS. | |
