Dermatan 4-sulfotransferase

Dermatan 4-sulfotransferase (, "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") is an enzyme with systematic name "3'-phospho-5'-adenylyl sulfate:(dermatan)-N-acetyl-D-galactosamine 4-sulfotransferase". This enzyme catalyses the following chemical reaction
The sulfation takes place at the 4-position of N-acetyl-D-galactosamine residues of dermatan.
