Noncrystallographic symmetry (NCS) | NCS oper: (Code: given Matrix: (-0.462535, -0.028377, 0.886147), Vector: Details | THE ASYMMETRIC UNIT OF THE CRYSTAL CONTAINS TWO HETERODIMERIC MOLECULES, EACH WITH AN ALPHA CHAIN (CHAINS A AND C, CORRESPONDING TO GENE MUTB) AND A BETA CHAIN (CHAINS B AND D, CORRESPONDING TO GENE MUTA). MOLECULE 1 CONSISTS OF CHAINS A (ALPHA), B (BETA), WITH GLYCEROL (RESIDUE 3001) AND WATERS (1-580). MOLECULE 2 CONSISTS OF CHAINS C (ALPHA), D (BETA), WITH GLYCEROL (RESIDUE 3002) AND WATERS (581-1155). CHAIN A INCLUDES COENZYME B12 (RESIDUE 1800) AND THE INHIBITOR 3-CARBOXYPROPYL-COA (RESIDUE 1801). CHAIN C INCLUDES COENZYME B12 (RESIDUE 2800) AND THE INHIBITOR 3-CARBOXYPROPYL-COA (RESIDUE 2801). | |
