Is commonly produced by soil microorganisms and plays an important role in the mineralization of sulfates. an aryl sulfate + H2O = a phenol + H(+) + sulfate Binds 1 Ca(2+) ion per subunit. Inhibited by Na(3)BO(3) and KCN. No inhibition by sodium dodecyl sulfate, even at high concentration. Optimum pH is 8.0. Optimum temperature is 60 degrees Celsius. Thermostable. By sulfur deprivation. 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. Belongs to the sulfatase family.
