โฆ Synopsis
The pepM gene coding for a methionine-specific aminopeptidase was cloned from Salmonella typhimurium and its nucleotide sequence determined. The gene encoded a 264 amino acid protein that was homologous to a similar protein from Escherichia coli. The sequence of an overproducer mutant allele, pepM100, contained a single base change in the likely--35 region of the pepM promoter that increased its homology to the consensus promoter sequence. A region downstream from the pepM coding sequence contained extensive inverted repeats and was homologous to sequences found elsewhere in both Salmonella and other bacterial species.

We have sequenced the fruR gene and flanking DNA fragments from Escherichia coli K12 and Salmonella typhimurium LT2. The fruR gene codes for a protein that represses the fru operon and activates the pps gene for PEP synthase. The corresponding open reading frame (ORF) FruR consists of 334 amino acid
