2022, Advanced Drug Delivery ReviewsCitation Excerpt :The ASA enzyme undergoes several post-translational modifications including incorporation of M6P [4,93], conversion of Cys69 to N-formyl glycine by SUMF1 [271–273], cleavage of a 7 kDa carboxyl terminal fragment [274], binding to a saposin B co-factor [275], and formation of octameric structures in the acid pH of the lysosome [276,277]. Recombinant human ASA was produced in CHO cells [93] with an enzyme specific activity of 60 units/mg based on the spectrophotometric enzyme assay using 4-nitro-catechol sulfate (NCS) as enzyme substrate [278], where 1 unit = 1 umol/min [279]. The NCS substrate is hydrolyzed by all tissue-sulfatases [280], and this this substrate cannot be used to determined ASA enzyme activity in brain (Table 5).
