Alpha-1,3-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase (EC 2.4.1.101, N-acetylglucosaminyltransferase I, N-glycosyl-oligosaccharide-glycoprotein N-acetylglucosaminyltransferase I, uridine diphosphoacetylglucosamine-alpha-1,3-mannosylglycoprotein beta-1,2-N-acetylglucosaminyltransferase, UDP-N-acetylglucosaminyl:alpha-1,3-D-mannoside-beta-1,2-N-acetylglucosaminyltransferase I, UDP-N-acetylglucosaminyl:alpha-3-D-mannoside beta-1,2-N-acetylglucosaminyltransferase I, alpha-1,3-mannosyl-glycoprotein beta-1,2-N-acetylglucosaminyltransferase, GnTI) is an enzyme with systematic name UDP-N-acetyl-D-glucosamine:3-(alpha-D-mannosyl)-beta-D-mannosyl-glycoprotein 2-beta-N-acetyl-D-glucosaminyltransferase.[1][2][3][4][5][6][7][8] This enzyme catalyses the following chemical reaction
- UDP-N-acetyl-D-glucosamine + 3-(alpha-D-mannosyl)-beta-D-mannosyl-R [math]\displaystyle{ \rightleftharpoons }[/math] UDP + 3-(2-[N-acetyl-beta-D-glucosaminyl]-alpha-D-mannosyl)-beta-D-mannosyl-R
R represents the remainder of the N-linked oligosaccharide in the glycoprotein acceptor.
