Metabolite Identification
Common NameChondroitin 6-sulfate
DescriptionChondroitin 6-sulfate, also known as chondroitin sulfate C, is a derivative of chondroitin which has a sulfate moiety esterified to carbon 6 of the N-acetylgalactosamine (GalNAc) sugar. Chondroitin sulfate (CS) is a linear heteropolysaccharide consisting of repeating disaccharide units of glucuronic acid and galactosamine, which is commonly sulfated at C-4 and/or C-6 of galactosamine. Chondroitin sulfate is a glycosaminoglycan (GAG) covalently linked to proteins forming proteoglycans (PGs). GAGs are all anionic linear heteropolysaccharide chains of repeating disaccharide units. According to the monosaccharide types and the glycosidic bonds between them, GAGs are divided into (1) hyaluronan, (2) CS and dermatan sulfate (DS), (3) heparan sulfate and heparin, and (4) keratan sulfate. CS was isolated from cartilage in 1884, but the nature of its monosaccharides and structure was first described in 1925. On the basis of the structure of chondroitin sulfate, at least five enzyme activities could be predicted, including three transferases (EC 2.4.1.79, the initiating GalNAc transferase; EC 2.4.1.175, polymerizing GalNAc; and EC 2.4.1.17, GlcA transferase) and two sulfotransferases (EC 2.8.2.5, GalNAc 4-sulfotransferase and EC 2.8.2.17, GalNAc 6-sulfotransferase). Additional enzymes exist for the epimerization of GlcA, sulfation of the uronic acids, and other patterns of sulfation found in unusual species of chondroitin. Chondroitin sulfate assembly can occur on virtually all proteoglycans, depending on the cell in which the core protein is expressed. Chondroitin sulfates from different sources vary in the location of sulfate groups. Separation of the products reveals that many types of chondroitin sulfate exist in nature but many chains are hybrid structures containing more than one type of disaccharide. Animal cells also degrade chondroitin sulfate in lysosomes using a series of exoglycolytic activities (PMID: 8993162 ). Chondroiton sulfate is a polymer that can contain up to 100 individual sugars.

Enzymes

General function:
Involved in sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of the N-acetylgalactosamine (GalNAc) residue of chondroitin. Chondroitin sulfate constitutes the predominant proteoglycan present in cartilage and is distributed on the surfaces of many cells and extracellular matrices. Can also sulfate Gal residues of keratan sulfate, another glycosaminoglycan, and the Gal residues in sialyl N-acetyllactosamine (sialyl LacNAc) oligosaccharides. May play a role in the maintenance of naive T-lymphocytes in the spleen.

General function:
Involved in sulfotransferase activity
Specific function:
Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of non-reducing N-acetylglucosamine (GlcNAc) residues. Preferentially acts on mannose-linked GlcNAc. Also able to catalyze the transfer of sulfate to position 6 of the N-acetylgalactosamine (GalNAc) residue of chondroitin. Also acts on core 2 mucin-type oligosaccharide and N-acetyllactosamine oligomer with a lower efficiency. Has weak or no activity toward keratan sulfate and oligosaccharides containing the Galbeta1-4GlcNAc. Catalyzes 6-O-sulfation of beta-benzyl GlcNAc but not alpha- or beta-benzyl GalNAc.
