In enzymology a N-acetylgalactosaminyl-proteoglycan 3-beta-glucuronosyltransferase (EC 2.4.1.226) is an enzyme that catalyzes the chemical reactionUDP-alpha-D-glucuronate + N-acetyl-beta-D-galactosaminyl-(1->4)-beta-D-glucuronosyl- proteoglycan UDP + beta-D-glucuronosyl-(1->3)-N-acetyl-beta-D-galactosaminyl-(1->4)- beta-D-glucuronosyl-proteoglycanThe 3 substrates of this enzyme are UDP-alpha-D-glucuronate [[N-acetyl-beta-D-galactosaminyl-(1->4)-beta-D-glucuronosyl-]] and proteoglycan whereas its 3 products are UDP [[beta-D-glucuronosyl-(1->3)-N-acetyl-beta-D-galactosaminyl-(1->4)-]] and beta-D-glucuronosyl-proteoglycan.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
