Alkylsulfatase that cleaves the widely used detergent sodium dodecyl sulfate (SDS), which allows the bacterium to use SDS as a sole carbon or sulfur source. a primary linear alkyl sulfate ester + H2O = a primary alcohol + H(+) + sulfate Binds 2 Zn(2+) ions per subunit. Transcriptionally regulated by SdsB. Belongs to the metallo-beta-lactamase superfamily. Type III sulfatase family. The N-terminus is shorter than orthologs.
