Accepted name: |
arylsulfatase (type I) |
Reaction: |
an aryl sulfate + H2O = a phenol + sulfate |
Other name(s): |
sulfatase; nitrocatechol sulfatase; phenolsulfatase; phenylsulfatase; p-nitrophenyl sulfatase; arylsulfohydrolase; 4-methylumbelliferyl sulfatase; estrogen sulfatase; type I sulfatase; arylsulfatase |
Systematic name: |
aryl-sulfate sulfohydrolase |
Comments: |
Sulfatase enzymes are classified as type I, in which the key catalytic residue is 3-oxo-L-alanine, type II, which are non-heme iron-dependent dioxygenases, or type III, whose catalytic domain adopts a metallo-β-lactamase fold and binds two zinc ions as cofactors. Arylsulfatases are type I enzymes, found in both prokaryotes and eukaryotes, with rather similar specificities. The key catalytic residue 3-oxo-L-alanine initiates the reaction through a nucleophilic attack on the sulfur atom in the substrate. This residue is generated by posttranslational modification of a conserved cysteine or serine residue by EC 1.8.3.7, formylglycine-generating enzyme, EC 1.1.98.7, serine-type anaerobic sulfatase-maturating enzyme, or EC 1.8.98.7, cysteine-type anaerobic sulfatase-maturating enzyme. |
