ID 3.1.6.19 DE (R)-specific secondary-alkylsulfatase (type III). AN (R)-specific sec-alkylsulfatase. AN (R)-specific secondary-alkylsulfatase. AN sec-alkylsulfatase. CA an (R)-secondary-alkyl sulfate + H2O = an (S)-secondary-alcohol + CA sulfate. CC -!- Sulfatase enzymes are classified as type I, in which the key CC catalytic residue is 3-oxo-L-alanine, type II, which are non-heme CC iron-dependent dioxygenases, or type III, whose catalytic domain CC adopts a metallo-beta-lactamase fold and binds two zinc ions as CC cofactors. CC -!- This enzyme belongs to the type III sulfatase family. CC -!- The enzyme from the bacterium Rhodococcus ruber prefers linear CC secondary-alkyl sulfate esters, particularly octan-2-yl, octan-3-yl, CC and octan-4-yl sulfates. CC -!- The enzyme from the bacterium Pseudomonas sp. DSM6611 utilizes a CC range of secondary-alkyl sulfate esters bearing aromatic, olefinic CC and acetylenic moieties. CC -!- Hydrolysis proceeds through inversion of the configuration at the CC stereogenic carbon atom, resulting in perfect enantioselectivity. cf. CC EC 1.14.11.77 and EC 3.1.6.1.
