Reaction: S-adenosyl-L-methionine + a [sulfatase]-L-cysteine + H2O = a [sulfatase]-3-oxo-L-alanine + 5'-deoxyadenosine + L-methionine + hydrogen sulfide
Glossary: 3-oxo-L-alanine = formylglycine = Cα-formylglycine = FGly
Other name(s): anSME; Cys-type anaerobic sulfatase-maturating enzyme; anaerobic sulfatase maturase
Systematic name: [sulfatase]-L-cysteine:S-adenosyl-L-methionine oxidoreductase (3-oxo-L-alanine-forming)
Comments: A radical S-adenosylmethionine (AdoMet) enzyme that contains three [4Fe-4S] clusters. The enzyme, found in some bacteria, activates a type I sulfatase enzyme (EC 3.1.6.1) by converting a conserved L-cysteine residue in the active site to a unique 3-oxo-L-alanine residue that is essential for the sulfatase activity. Some enzymes can also act on L-serine, see EC 1.1.98.7, serine-type anaerobic sulfatase-maturating enzyme and EC 1.8.3.7, formylglycine-generating enzyme.
