1 Towards isatin, wild-type CBR3 showed a catalytic efficiency of 0.018 microM(-1)min(-1), whereas wild-type CBR1 showed a catalytic efficiency of 13.5 microM(-1)min(-1). Isatin carbonyl reductase 1 Homo sapiens
2 In particular, when nine residues (236-244) in the vicinity of the catalytic center and a proline (P230) in CBR3 were mutated to the corresponding residues of CBR1 a much higher k(cat)/K(m) value (5.7 microM(-1)min(-1)) towards isatin was observed. Isatin carbonyl reductase 1 Homo sapiens
