EC 2.8.2.35

Accepted name: dermatan 4-sulfotransferase

Reaction: 3'-phospho-5'-adenylyl sulfate + [dermatan]-N-acetyl-D-galactosamine = adenosine 3',5'-bisphosphate + [dermatan]-4-O-sulfo-N-acetyl-D-galactosamine

Glossary: 3'-phosphoadenylyl sulfate = PAPS

Other name(s): dermatan-specific N-acetylgalactosamine 4-O-sulfotransferase; dermatan-4-sulfotransferase-1; dermatan-4-sulfotransferase 1; D4ST-1; dermatan N-acetylgalactosamine 4-O-sulfotransferase; CHST14 protein; CHST14

Systematic name: 3'-phospho-5'-adenylyl sulfate:[dermatan]-N-acetyl-D-galactosamine 4-sulfotransferase

Comments: The sulfation takes place at the 4-position of N-acetylgalactosamine residues of dermatan. D4ST-1 shows a strong preference in vitro for sulfate transfer to IdoUAα(1,3)GalNAcβ(1,4) that is flanked by GlcUAβ(1,3)GalNAcβ(1,4) as compared with IdoUAα(1,3)GalNAcβ(1,4) flanked by IdoUAα(1,3)GalNAcβ(1,4) [1].
