IntEnz Enzyme Nomenclature
EC 3.1.3.71

Names

Accepted name:
2-phosphosulfolactate phosphatase
Other names:
(2R)-phosphosulfolactate phosphohydrolase
ComB phosphatase
Systematic name:
(R)-2-phospho-3-sulfolactate phosphohydrolase

Reaction

Cofactor

Comments:

Requires Mg2+. The enzyme from Methanococcus jannaschii acts on both stereoisoimers of the substrate and also hydrolyses a number of phosphate monoesters of (S)-2-hydroxycarboxylic acids, including 2-phosphomalate, 2-phospholactate and 2-phosphoglycolate. This enzyme can also hydrolyze phosphate monoesters of (R)-2-hydroxycarboxylic acids such as (S)-2-phospho-3-sulfolactate and (R)-2-phosphomalate, which, presumably, bind to the enzyme in opposite orientations.
