Steroid sulfatase (STS), or steryl-sulfatase (EC 3.1.6.2), formerly known as arylsulfatase C, is a sulfatase enzyme involved in the metabolism of steroids. It is encoded by the STS gene.[1]

Reactions

This enzyme catalyses the following chemical reaction

3β-hydroxyandrost-5-en-17-one 3-sulfate + H2O <math>\rightleftharpoons</math> 3β-hydroxyandrost-5-en-17-one + sulfate

Also acts on some related steryl sulfates.

Function

The protein encoded by this gene catalyzes the conversion of sulfated steroid precursors to the free steroid. This includes DHEA sulfate, estrone sulfate, pregnenolone sulfate, and cholesterol sulfate, all to their unconjugated forms (DHEA, estrone, pregnenolone, and cholesterol, respectively).[2][3] The encoded protein is found in the endoplasmic reticulum, where it is present as a homodimer.[1]

Clinical significance

A congenital deficiency in the enzyme is associated with X-linked ichthyosis, a scaly-skin disease affecting roughly 1 in every 2,000 to 6,000 males.[5][6] The excessive skin scaling or hyperkeratosis is caused by a lack of breakdown and thus accumulation of cholesterol sulfate, a steroid that stabilizes cell membranes and adds cohesion, in the outer layers of the skin.[2]

Steroid sulfates like DHEA sulfate and estrone sulfate serve as large biologically inert reservoirs for conversion into androgens and estrogens, respectively, and hence are of significance for androgen- and estrogen-dependent conditions like prostate cancer, breast cancer, endometriosis, and others.

Inhibitors

Inhibitors of STS include irosustat, estrone sulfamate (EMATE), estradiol sulfamate (E2MATE), and danazol.[7][8]

Names

Steryl-sulfatase is also known as arylsulfatase, steroid sulfatase, sterol sulfatase, dehydroepiandrosterone sulfate sulfatase, arylsulfatase C, steroid 3-sulfatase, steroid sulfate sulfohydrolase, dehydroepiandrosterone sulfatase, pregnenolone sulfatase, phenolic steroid sulfatase, 3-beta-hydroxysteroid sulfate sulfatase, as well as by its systematic name steryl-sulfate sulfohydrolase.[9][10][11]
