Alkyl/aryl-sulfatase. Enables the use of SDS and 4-nitrocatechol as sulfur source. Binds 2 Zn(2+) ions per subunit. Expression is increased in sulfur-limited chemostat cultures. The presence of this bacterial-like protein in S.cerevisiae results probably from a recent horizontal gene transfer event. Belongs to the metallo-beta-lactamase superfamily. Type III sulfatase family.
