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

✦ Synopsis
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.

## Abstract Highly purified ribose‐binding protein from Escherichia coli has been used to reconstitute a binding‐protein‐dependent ribose transport in spheroplasts derived from a binding‐protein‐deficient mutant of E coli K 12, and in spheroplasts derived from Salmonella typhimurium. The cross‐spec
The most striking phenotype associated with superoxide dismutase (SOD) deficiency in Escherichia coli is the inability to grow in aerobic minimal medium, which is due to the sensitivity of several amino acid biosynthetic pathways to superoxide. We have isolated two classes of pseudorevertants that g
