Glossary: 3'-phosphoadenylyl sulfate = PAPS
glycolithocholate sulfate = N-(3α-sulfooxy-5β-cholan-24-oyl)glycine
Other name(s): BAST I; bile acid:3'-phosphoadenosine-5'-phosphosulfate sulfotransferase; bile salt:3'phosphoadenosine-5'-phosphosulfate:sulfotransferase; bile acid sulfotransferase I; glycolithocholate sulfotransferase
Systematic name: 3'-phosphoadenylyl-sulfate:glycolithocholate sulfotransferase
Comments: The formation of sulfate esters of bile acids is an essential step in the prevention of toxicity by monohydroxy bile acids in many species . This enzyme is both a bile salt and a 3-hydroxysteroid sulfotransferase. In addition to the 5β-bile acid glycolithocholate, deoxycholate, 3β-hydroxy-5-cholenoate and dehydroepiandrosterone (3β-hydroxyandrost-5-en-17-one) also act as substrates [see also EC 18.104.22.168 (alcohol sulfotransferase) and EC 22.214.171.124 (glycochenodeoxycholate sulfotransferase)]. May be identical to EC 126.96.36.199 .
