ID 3.1.6.22 DE branched primary-alkylsulfatase. AN type III branched primary-alkylsulfatase. CA 2-butyloctyl sulfate + H2O = 2-butyloctan-1-ol + H(+) + 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 family. CC -!- The enzyme, characterized from a Pseudomonas strain, is specific for CC branched primary-alkyl sulfate esters and does not act on linear CC substrates such as dodecyl sulfate. cf. EC 1.14.11.77, EC 3.1.6.1, CC EC 3.1.6.19, and EC 3.1.6.21. //
