| Abstract: | N-Acetyl-D-glucosaminylpyrophosphorylundecaprenol (GlcNAc-P-P-Und),an intermediate in the biosynthesis of the enterobacterial commonantigen in E.coli and some O-antigen chains in gram-negativebacteria, is formed by the transfer of GlcNAc 1-P from UDP-GlcNActo Und-P, analogous to the reaction forming GlcNAc-P-P-dolichol(GlcNAc-P-P-Dol) in mammalian cells. Since the micro-somal enzymefrom animal cells exhibits a strong preference for Dol-P, whichcontains a saturated |
