ENZYME entry: EC 3.1.6.19

PURL: https://purl.expasy.org/enzyme/EC/3.1.6.19
Accepted Name
(R)-specific secondary-alkylsulfatase (type III)
Alternative Name(s)
(R)-specific sec-alkylsulfatase
(R)-specific secondary-alkylsulfatase
sec-alkylsulfatase
Reaction catalysed
an (R)-secondary-alkyl sulfate + H2O = an (S)-secondary-alcohol + sulfate
Comment(s)
  • 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-beta-lactamase fold and binds two zinc ions as cofactors.
  • This enzyme belongs to the type III sulfatase family.
  • The enzyme from the bacterium Rhodococcus ruber prefers linear secondary-alkyl sulfate esters, particularly octan-2-yl, octan-3-yl, and octan-4-yl sulfates.
  • The enzyme from the bacterium Pseudomonas sp. DSM6611 utilizes a range of secondary-alkyl sulfate esters bearing aromatic, olefinic and acetylenic moieties.
  • Hydrolysis proceeds through inversion of the configuration at the stereogenic carbon atom, resulting in perfect enantioselectivity. cf. EC 1.14.11.77 and EC 3.1.6.1.
