Details | THE ACTIVE ENZYME IS A HEXAMER. THE ASYMMETRIC UNIT OF THIS CRYSTAL FORM CONTAINS A MONOMER OF THE ACTIVE HEXAMER. THE WHOLE HEXAMER CAN BE GENERATED AS FOLLOWS I) APPLY TWICE THE CRYSTALLOGRAPHIC THREE-FOLD ROTATION OPERATION AROUND C-AXIS TO GENERATE A TRIMER. II) ROTATE THE TRIMER AROUND THE CRYSTALLOGRAPHIC TWO-FOLD AND TRANSLATE (0. 0. 1.) IN FRACTIONAL UNITS. 1.5 B=111.5 C=76.5 |
