The enzyme choline-sulfatase (EC 3.1.6.6) catalyzes the reaction
The enzyme characterised from Pseudomonas nitroreducens and Sinorhizobium meliloti hydrolyses choline sulfate to choline and sulfate. A similar enzyme has been found in Vreelandella titanicae.
This enzyme is a hydrolase, specifically one acting on sulfuric ester bonds. The systematic name is choline-sulfate sulfohydrolase.
