| Post Translational Modifications | N-glycosylated. N-glycosylated with both high mannose and complex type sugars. The conversion to 3-oxoalanine (also known as C-formylglycine, FGly), of a serine or cysteine residue in prokaryotes and of a cysteine residue in eukaryotes, is critical for catalytic activity. The 63-kDa precursor undergoes proteolytic processing in two steps, yielding two fragments in the first step (apparent molecular masses of 44 and 18 kDa). In the second step, the 44-kDa fragment is processed further to the 34- and 10-kDa chains. The 10-kDa chain is a cleavage product of the 44-kDa fragment but linked to the 18-kDa chain through a disulfide bridge. |
| Function | Displays arylsulfatase activity at acidic pH towards artificial substrates, such as p-nitrocatechol sulfate and also, but with a lower activity towards p-nitrophenyl sulfate and 4-methylumbelliferyl sulfate. Catalyzes the hydrolysis of the 3-sulfate groups of the N-sulfo-D-glucosamine 3-O-sulfate units of heparin. |
