The investigation of hydrolysis of p-nitrophenyl acetate (NPA) catalyzed by bovine serum albumin (BSA) proved that the initial rate in the steady state folows a Michaelis-Menten equation. In the use of D- and L-p-nitrophenyl α-methoxyphenlacetates (D- and L-NPMA's) as an enantiomeric ester, the L-enantiomer is hydrolyzed about three times faster than the D-enantiomer, mainly due to stronger binding
对牛血清白蛋白(BSA)催化的对硝基苯基乙酸酯(NPA)水解的研究证明,稳态下的初始速率遵循一个Michaelis-Menten方程。在使用D-和L-对硝基苯基α-甲氧基苯乙酸酯(D-和L-NPMA's)作为对映体酯时,L-对映体的水解速度比D-对映体快约三倍,主要是由于BSA的前对映体。
