A murC gene from coryneform bacteria.

The upstream flanking region of the ftsQ and ftsZ genes of Brevibacterium flavum MJ233, which belongs to the coryneform bacteria, was amplified by the inverse polymerase chain reaction method and cloned in Escherichia coli. Complementation analysis of E. coli mutant with a defective cell-wall synthesis mechanism with the cloned fragment and its DNA sequencing indicated the presence of the murC gene, encoding UDP-N-acetylmuramate:L-alanine ligase involved in peptidoglycan synthesis, just upstream from the ftsQ gene. The B. flavum murC gene could encode a protein of 486 amino acid residues with a calculated molecular mass of 51 198 Da. A 50-kDa protein was synthesized by the B. flavum murC gene in an in vitro transcription/translation system using E. coli S30 lysate. These results indicate that the genes responsible for cell-wall synthesis and cell division are located as a cluster in B. flavum similar to the E. coli mra region.[1]
