EC 1.8.3.7     
Accepted name: formylglycine-generating enzyme
Reaction: a [sulfatase]-L-cysteine + O2 + 2 a thiol = a [sulfatase]-3-oxo-L-alanine + hydrogen sulfide + a disulfide + H2O
Glossary: 3-oxo-L-alanine = formylglycine = Cα-formylglycine = FGly
Other name(s): sulfatase-modifying factor 1; Cα-formylglycine-generating enzyme 1; SUMF1 (gene name)
Systematic name: [sulfatase]-L-cysteine:oxygen oxidoreductase (3-oxo-L-alanine-forming)
Comments: Requires a copper cofactor and Ca2+. The enzyme, which is found in both prokaryotes and eukaryotes, catalyses a modification of a conserved L-cysteine residue in the active site of sulfatases, generating a unique 3-oxo-L-alanine residue that is essential for sulfatase activity. The exact nature of the thiol involved is still not clear - dithiothreitol and cysteamine are the most efficiently used thiols in vitro. Glutathione alo acts in vitro, but it is not known whether it is used in vivo.
