The enzyme D-lactate-2-sulfatase (EC 3.1.6.17) catalyzes the reaction
The enzyme characterised from Pseudomonas syringae hydrolyses (R)-2-O-sulfolactic acid to (R)-lactic acid and sulfate.
This enzyme is a hydrolase, specifically one acting on sulfuric ester bonds. The systematic name is (R)-2-O-sulfolactate 2-sulfohydrolase. Another name (S)-2-O-sulfolactate 2-sulfohydrolase specifies the stereochemistry incorrectly.
