Deficiencies in the enzymatic activity of acid sphingomyelinase (ASM) result in Niemann-Pick disease. A variety of modifications which eliminate the activity of the free thiol on the C-terminal cysteine residue of ASM all result in substantially increased specific activity of the enzyme. Methods used to alter the activity of this residue include site-directed mutagenesis to delete or alter the residue, enzymatic degradation of the ASM to remove the residue, copper-promoted dimerization of ASM (via the terminal cysteine residues) and chemical modification of the free thiol group on this residue.
酸性鞘磷脂酶(ASM)的酶活性不足会导致尼曼-皮克病。 消除 ASM C 端半胱氨酸残基上游离硫醇活性的各种修饰都能显著提高酶的特异性活性。 用于改变该残基活性的方法包括:定点突变以删除或改变该残基、酶降解 ASM 以去除该残基、铜促进 ASM 的二聚化(通过末端半胱氨酸残基)以及对该残基上的游离硫醇基团进行化学修饰。
