- UDP-N-acetyl-D-glucosamine + dolichyl phosphate UMP + N-acetyl-D-glucosaminyl-diphosphodolichol
Thus, the two substrates of this enzyme are UDP-N-acetyl-D-glucosamine and dolichyl phosphate, whereas its two products are UMP and N-acetyl-D-glucosaminyl-diphosphodolichol.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups transferases for other substituted phosphate groups. The systematic name of this enzyme class is UDP-N-acetyl-D-glucosamine:dolichyl-phosphate N-acetyl-D-glucosaminephosphotransferase. Other names in common use include UDP-D-N-acetylglucosamine N-acetylglucosamine 1-phosphate transferase, UDP-GlcNAc:dolichyl-phosphate GlcNAc-1-phosphate transferase, UDP-N-acetyl-D-glucosamine:dolichol phosphate N-acetyl-D-glucosamine-1-phosphate transferase, uridine diphosphoacetylglucosamine-dolichyl phosphate acetylglucosamine-1-phosphotransferase, chitobiosylpyrophosphoryldolichol synthase, dolichol phosphate N-acetylglucosamine-1-phosphotransferase, UDP-acetylglucosamine-dolichol phosphate acetylglucosamine phosphotransferase, and UDP-acetylglucosamine-dolichol phosphate acetylglucosamine-1-phosphotransferase. This enzyme participates in the biosynthesis of N-glycan and glycan structures.
