Other name(s): (2R)-phosphosulfolactate phosphohydrolase; ComB phosphatase
Systematic name: (R)-2-phospho-3-sulfolactate phosphohydrolase
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 hydrolyse 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.
