EC 2.8.2.5

Accepted name: chondroitin 4-sulfotransferase

Reaction: 3'-phosphoadenylyl sulfate + chondroitin = adenosine 3',5'-bisphosphate + chondroitin 4'-sulfate

Glossary: 3'-phosphoadenylyl sulfate = PAPS

Other names: chondroitin sulfotransferase

Systematic name: 3'-phosphoadenylyl-sulfate:chondroitin 4'-sulfotransferase

Comments: The sulfation takes place at the 4-position of N-acetyl-galactosamine residues of chondroitin. Not identical with EC 2.8.2.17 chondroitin 6-sulfotransferase.
