EC 2.8.2.34

Accepted name: glycochenodeoxycholate sulfotransferase

Reaction: 3'-phosphoadenylyl sulfate + glycochenodeoxycholate = adenosine 3',5'-bisphosphate + glycochenodeoxycholate 7-sulfate

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 2.8.2.14 bile-salt sulfotransferase). The monohydroxy bile acids glycolithocholate, chenodeoxycholate and ursodeoxycholate act as inhibitors.
