BRITE hierarchy
Sysname
3'-phosphoadenylyl-sulfate:[dermatan]-4-O-sulfo-N-acetyl-D-galactosamine 6-O-sulfotransferase
Reaction(IUBMB)
(1) 3'-phospho-5'-adenylyl sulfate + [dermatan]-4-O-sulfo-N-acetyl-D-galactosamine = adenosine 3',5'-bisphosphate + [dermatan]-4,6-di-O-sulfo-N-acetyl-D-galactosamine [RN:R10868];
(2) 3'-phospho-5'-adenylyl sulfate + [chondroitin]-4-O-sulfo-N-acetyl-D-galactosamine = adenosine 3',5'-bisphosphate + [chondroitin]-4,6-di-O-sulfo-N-acetyl-D-galactosamine [RN:R10869]
Reaction(KEGG)
Substrate
3'-phospho-5'-adenylyl sulfate [CPD:C00053];
[dermatan]-4-O-sulfo-N-acetyl-D-galactosamine;
[chondroitin]-4-O-sulfo-N-acetyl-D-galactosamine
Product
adenosine 3',5'-bisphosphate [CPD:C00054];
[dermatan]-4,6-di-O-sulfo-N-acetyl-D-galactosamine;
[chondroitin]-4,6-di-O-sulfo-N-acetyl-D-galactosamine
Comment
The enzyme is activated by divalent cations and reduced glutathione. The enzyme from human transfers sulfate to position 6 of both internal residues and non-reducing terminal GalNAc 4-sulfate residues of chondroitin sulfate and dermatan sulfate. Oligosaccharides derived from chondroitin sulfate also serve as acceptors but chondroitin sulfate E, keratan sulfate and heparan sulfate do not. Differs from EC 2.8.2.17, chondroitin 6-sulfotransferase, in being able to use both chondroitin and dermatan as effective substrates
History
EC 2.8.2.33 created 2005, modified 2010
Pathway
Glycosaminoglycan biosynthesis - chondroitin sulfate / dermatan sulfate
