In enzymology, a glycochenodeoxycholate sulfotransferase (EC 2.8.2.34) is an enzyme that catalyzes the chemical reaction 3'-phosphoadenylyl sulfate + glycochenodeoxycholate adenosine 3',5'-bisphosphate + glycochenodeoxycholate 7-sulfate Thus, the two substrates of this enzyme are 3'-phosphoadenylyl sulfate and , whereas its two products are adenosine 3',5'-bisphosphate and .
