A defect in the repression of the de novo purine biosynthetic enzymes was detected among purA mutants of Salmonella typhimurium. We suggest that the defect is caused by an altered purine regulation gene (purR) which affects the response level of at least five of the de novo enzymes to repression by

## Abstract The effect of inhibitors and uncouplers on the osmotic shock‐sensitive transport systems for glutamine and galactose (by the β‐methyl galactoside permease) was compared to their effect on the osmotic shock‐resistant proline and galactose permease systems in cytochrome‐deficient cells of
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 __Salmonella typhimurium__ strain 4a is a temperature‐sensitive division mutant. At 39° or 42° in several media a septation lesion occurs since non‐septate filaments form at these temperatures. At lower temperatures in some media separation is aberrant since long chains of cells are for
