ID 1.1.98.7 DE serine-type anaerobic sulfatase-maturating enzyme. CA L-seryl-[sulfatase] + S-adenosyl-L-methionine = 3-oxo-L-alanyl- CA [sulfatase] + 5'-deoxyadenosine + H(+) + L-methionine. CC -!- A bacterial radical S-adenosyl-L-methionine (AdoMet) enzyme that CC contains three [4Fe-4S] clusters. CC -!- The enzyme, found in some bacteria, activates a type I sulfatase CC enzyme (EC 3.1.6.1) by converting a conserved L-serine residue in the CC active site to a unique 3-oxo-L-alanine residue that is essential for CC the sulfatase activity. CC -!- While the enzyme from Klebsiella pneumoniae is specific for L-serine, CC the enzyme from Clostridium perfringens can also act on L-cysteine, CC see EC 1.8.98.7.
