ENZYME entry: EC 3.1.6.21

PURL: https://purl.expasy.org/enzyme/EC/3.1.6.21
Accepted Name
linear primary-alkylsulfatase
Alternative Name(s)
type III linear primary-alkylsulfatase
Reaction catalysed
a primary linear alkyl sulfate ester + H2O = a primary alcohol + sulfate + H(+)
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 is active against linear primary-alkyl sulfate esters, such as dodecyl sulfate, decyl sulfate, octyl sulfate, and hexyl sulfate.
  • The enzyme from Pseudomonas aeruginosa is secreted out of the cell.
  • The catalytic mechanism begins with activation of a water molecule by the binuclear Zn(2+) cluster, resulting in a nucleophilic attack on the carbon atom. cf. EC 3.1.6.19 and EC 3.1.6.22.
