Metabolite Identification
Common NameN-Acetylgalactosamine 4-sulphate
DescriptionAlso known as GalNAc4S, this molecule is a key component of dermatan, keratan and chondroitin sulfate. It is also a substrate for the enzyme N-acteylgalactosamine-4-sulphate transferase. This molecule is found in elevated concentrations in the urine of patients suffering from muchopolysaccharidosis type III, IV and VI. Levels are typically 300-400 times normal values. GalNAc4S is thought to be derived from the action of beta-N-acetylhexosaminidase on sulphated GlcNAc or GalNAc residues at the non-reducing end of keratan sulphate, dermatan sulphate or chondroitin sulphate.

Enzymes

General function:
Involved in catalytic activity
Specific function:
May have a role in promoting tumor progression. May block the TGFB1-enhanced cell growth.

+ Water → DWA-2 + N-Acetylgalactosamine 4-sulphatedetails
General function:
Involved in catalytic activity
Specific function:
Involved in sperm-egg adhesion. Upon fertilization sperm must first penetrate a layer of cumulus cells that surrounds the egg before reaching the zona pellucida. The cumulus cells are embedded in a matrix containing hyaluronic acid which is formed prior to ovulation. This protein aids in penetrating the layer of cumulus cells by digesting hyaluronic acid.

General function:
Involved in catalytic activity
Specific function:
Hydrolyzes high molecular weight hyaluronic acid to produce an intermediate-sized product which is further hydrolyzed by sperm hyaluronidase to give small oligosaccharides. Displays very low levels of activity. Associates with and negatively regulates MST1R.
