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. |
