Four closely related uridine nucleotide-peptides isolated from ethanol extracts of penicillin-treated Aerobacter cloacae NRC 492 have been partially characterized. Fractionation of dialyzed extracts on Dowex-1-Cl columns with aqueous lithium chloride solutions, precipitation of the nucleotide-peptides with methanol–acetone, and further separation by paper chromatography and high voltage electrophoresis yielded (a) UDP-GNAc-lact.L-ala.D-glu.meso-dap.D-ala,* (b) UDP-GNAc-lact.L-ala.D-glu.meso-dap, (c) UDP-GNAc-lact.L-ala.D-glu., and (d) UDP-GNAc-lactic acid. The amino acid isomers were identified by micro-enzymic and chromatographic methods.
