2.7.8.33 | UDP-N-acetyl-alpha-D-glucosamine + ditrans,octacis-undecaprenyl phosphate = UMP + N-acetyl-alpha-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol |
a one-step, single displacement mechanism. The oxyanion of the polyprenyl-phosphate attacks the beta-phosphate of the nucleotide substrate, leading to the formation of lipid product and the liberation of UMP. The involvement of an invariant aspartyl residue in the deprotonation of the lipid substrate is possible |
