Glossary: 3'-phosphoadenylyl sulfate = PAPS
glycochenodeoxycholate 7-sulfate = N-(3α-hydroxy-7α-sulfooxy-5β-cholan-24-oyl)glycine
Other name(s): bile acid:3'-phosphoadenosine-5'-phosphosulfate sulfotransferase; bile acid:PAPS:sulfotransferase; BAST
Systematic name: 3'-phosphoadenylyl-sulfate:glycochenodeoxycholate 7-sulfotransferase
Comments: The enzyme specifically sulfates glycochenodeoxycholate at the 7α-position (see also EC 22.214.171.124 bile-salt sulfotransferase). The monohydroxy bile acids glycolithocholate, chenodeoxycholate and ursodeoxycholate act as inhibitors.
