Protein

Exostosin-1

Gene

EXT1

Organism
Papio anubis (Olive baboon)
Status
Reviewed - Annotation score: 5 out of 5- Protein inferred from homologyi

Functioni

Glycosyltransferase required for the biosynthesis of heparan-sulfate. The EXT1/EXT2 complex possesses substantially higher glycosyltransferase activity than EXT1 or EXT2 alone (By similarity).By similarity

Catalytic activityi

UDP-N-acetyl-D-glucosamine + beta-D-glucuronosyl-(1->4)-N-acetyl-alpha-D-glucosaminyl-proteoglycan = UDP + N-acetyl-alpha-D-glucosaminyl-(1->4)-beta-D-glucuronosyl-(1->4)-N-acetyl-alpha-D-glucosaminyl-proteoglycan.
UDP-alpha-D-glucuronate + N-acetyl-alpha-D-glucosaminyl-(1->4)-beta-D-glucuronosyl-proteoglycan = UDP + beta-D-glucuronosyl-(1->4)-N-acetyl-alpha-D-glucosaminyl-(1->4)-beta-D-glucuronosyl-proteoglycan.
