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 name(s):

chondroitin sulfotransferase; 3′-phosphoadenylyl-sulfate:chondroitin 4′-sulfotransferase

Systematic name:

3′-phosphoadenylyl-sulfate:chondroitin 4′-sulfonotransferase

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.
