Alkylsulfatase that catalyzes the enantioselective hydrolysis of secondary-alkylsulfates with strict inversion of configuration, leading to the formation of homochiral (S)-configurated alcohols and nonreacted sulfate esters (PubMed:21770430, Ref.2, PubMed:23061549). The substrate spectrum includes a range of linear, branched or cyclic sec-alkylsulfates (PubMed:21770430). Can use sec-alkylsulfate esters bearing aromatic, olefinic and acetylenic moieties (Ref.2). Acts by cleaving the C-O bond, resulting in inversion at the carbon (PubMed:23061549). an (R)-secondary-alkyl sulfate + H2O = an (S)-secondary-alcohol + sulfate. kcat is 262 min(-1) with (R)-2-octyl sulfate as substrate. kcat is 52 min(-1) with 1-octyl sulfate as substrate. Is very stable at 20-30 degrees Celsius. Homodimer. Is a very useful inverting alkylsulfatase for the deracemisation of rac-sec-alcohols via enzymatic hydrolysis of their corresponding sulfate esters, which furnishes homochiral products. Belongs to the metallo-beta-lactamase superfamily. Type III sulfatase family.
