the appearance of 430-nm species upon incubation of c ( no2 ) 4-inactivated apoenzyme with pyridoxal-p indicated that the c ( no2 ) 4-inactivated apoenzyme could still bind the coenzyme , although an affinity of the enzyme for pyridoxal-p ( kd = 51 microm ) was much lower than that of the native enzyme ( kd = 0.7 microm ) .
