N-acetylglucosaminyldiphosphodolichol N-acetylglucosaminyltransferase (EC 2.4.1.141, UDP-GlcNAc:dolichyl-pyrophosphoryl-GlcNAc GlcNAc transferase, uridine diphosphoacetylglucosamine-dolichylacetylglucosamine pyrophosphate acetylglucosaminyltransferase, N,N'-diacetylchitobiosylpyrophosphoryldolichol synthase) is an enzyme with systematic name UDP-N-acetyl-D-glucosamine:N-acetyl-D-glucosaminyl-diphosphodolichol N-acetyl-D-glucosaminyltransferase.[1][2] This enzyme catalyses the following chemical reaction

UDP-N-acetyl-D-glucosamine \+ N-acetyl-D-glucosaminyl-diphosphodolichol  ⇌ {\displaystyle \rightleftharpoons } UDP + N,N'-diacetylchitobiosyl-diphosphodolichol
