| Abstract |
Temperature-sensitive mutants of Escherichia coli K-12 which cannot form cell wall peptidoglycan at 42 C were isolated. The thermosensitive steps were characterized biochemically, and the genes coding the enzymes of peptidoglycan synthesis were mapped. These genes were in two clusters: one group, located at about 1.5 min between leu and azi, was designated as mra (murein a); the second group, located at about 77.5 min close to argH and metB, was designated as mrb (murein b, with the order metB-argH-mrb). No simple relations were found between the gene location and the order or localization of enzymes involved in the sequence of reactions of cell wall peptidoglycan biosynthesis. |
