The enzyme Glycosulfatase (EC 3.1.6.3) catalyzes the reaction
The enzyme characterised from Littorina species hydrolyses D-glucose 6-sulfate to D-glucose (both shown in their aldehydo forms).
This enzyme bis a hydrolase, specifically one acting on sulfuric ester bonds. The systematic name of this enzyme class is sugar-sulfate sulfohydrolase. This enzyme is also called glucosulfatase.
