應用
猪肾中的酰化酶I已被用于研究各种S-烷基-N-乙酰基-L-半胱氨酸及其碳、氧类似物的酰化酶I催化的脱乙酰作用。 酰化酶I可能有助于催化N-乙酰氨基酸生成对映体纯的 L-氨基酸。
生化／生理作用
酰化酶I是一种锌金属蛋白，可催化非天然和很少发生的α氨基酸的动力学分解。它对N-酰基L-α-氨基酸水解的对映选择性几乎是绝对的，但它接受具有广泛结构和功能性的底物。酰化酶I催化N-乙酰基-L-半胱氨酸和S-烷基-N-乙酰基-L-半胱氨酸的脱乙酰化。正丁基丙二酸是酰化酶I的抑制剂。S-烷基-N-乙酰基-L-半胱氨酸与短(C0-C3)和不分枝S-烷基取代已被发现是良好的酰化酶I底物。

The aminoacylase that catalyzes the hydrolysis of N-acetyl-L-cysteine (NAC) was identified as acylase I after purification by column chromatography and electrophoretic analysis. Rat kidney cytosol was fractionated by ammonium sulfate precipitation, and the proteins were separated by ion-exchange column chromatography
