Endocrine steroid sulfotransferases: Porcine endometrial estrogen sulfotransferase
Journal of Steroid Biochemistry, 1987Porcine endometrial estrogen sulfotransferase has been isolated and its properties examined. This enzyme only appeared in uteri from ovariectomized gilts which had been primed with estrogen and treated with progesterone. The most stable form of the enzyme was obtained via chromatofocusing of the 100,000 g supernatant from secretory endometrium.

A Hydroxysteroid Sulfotransferase, St2b2, Is a Skin Cholesterol Sulfotransferase in Mice
Journal of Biochemistry, 2002The mRNA of a sulfotransferase (St2b2) mediating cholesterol sulfation was detected in mouse skin. Recombinant St2b2 also mediated the sulfation of pregnenolone, 3beta-hydroxy-5-cholen-24-oic acid, and dehydroepiandrosterone. St2b2 protein was detected in skin cytosols on Western blotting.

Inhibition of Sulfotransferases by Xenobiotics
Current Drug Metabolism, 2006The sulfotransferase (SULT) family comprises important phase II conjugation enzymes for the detoxification of xenobiotics and modulation of the activity of physiologically important endobiotics such as thyroid hormones, steroids, and neurotransmitters.

Sulfotransferases in glycosaminoglycan biosynthesis
Current Opinion in Structural Biology, 2003Most of the sulfotransferases participating in glycosaminoglycan biosynthesis have now been identified. Their essential role in generating binding sites for proteins interacting with glycosaminoglycans is apparent. These interactions may influence important biological processes such as growth control, signal transduction, cell adhesion and lipid ...

Sulfotransferases in the bioactivation of xenobiotics
Chemico-Biological Interactions, 2000Conjugation of xenobiotics is often associated with detoxification. However, this traditional view is one-sided. In particular, numerous compounds are known that are metabolized to chemically reactive metabolites via sulfation (O-sulfonation). This can be rationalized by the fact that the sulfate group is electron-withdrawing and may be cleaved off ...

Phenol sulfotransferase inheritance
Cellular and Molecular Neurobiology, 19881. Phenol sulfotransferase (PST) catalyzes the sulfate conjugation of many phenolic and catechol neurotransmitters. Human tissues contain both thermostable (TS) and thermolabile (TL) forms of PST that differ in their substrate specificities, inhibitor sensitivities, physical properties, and regulation. 2. Individual variations in the levels of activity
