A genetic study of mutants deficient in hydrogenase activity was performed. In E. coli, the affected gene (hyd) is located at 51 min, between cys C and nal B; in S. typhimurium, it probably lies in the homologous region of the chromosome.
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
