sulfatase

[′səl·fə‚tās]
(biochemistry)
Any of a group of esterases that catalyze the hydrolysis of sulfuric esters.

Sulfatase

 

(or sulfohydrolase), any one of several enzymes belonging to the class of hydrolases. Sulfatases catalyze the decomposition of sulfuric esters, with the release of a free sulfation. They are widespread in animals, plants, and microorganisms.

The known sulfatases act on various substrates. Aryl sulfatases hydrolyze aromatic sulfuric esters, glycosulfatases hydrolyze sulfuric esters of monosaccharides and disaccharides, chondrosulfatases decompose chondroitinsulfuric acid, sterol sulfatases hydrolyze steroid sulfuric esters, and cellulose sulfatases split the sulfo group from cellulose polysulfates. Aryl sulfatases have been studied in the greatest detail.
