NOVEL Escherichia coli dnaB mutant: direct involvement of the dnaB252 gene product in the synthesis of an origin-ribonucleic acid species during initiaion of a round of deoxyribonucleic acid replication.

abstract：:Five temperature-sensitive lysis mutants were found to possess very low diaminopimelic acid (Dpm) adding enzyme activity in vitro. Murein synthesis at 42 C was impaired, and uridine-5'-diphosphate-N-acetyl-muramyl-l-Ala- d-Glu (UDP-MurNAc-dipeptide) was accumulated. In the presence of NaCl, the mutants could grow at 4...
