Mutants of E. coli, completely devoid of nitrite reductase activity with glucose or formate as donor were studied. Biochemical analysis indicates that they are simultaneously affected in nitrate reductase, nitrite reductase, fumarate reductase and hydrogenase activities as well as in cytochrome C552

✦ Synopsis
A mutation affecting alanine-alpha-ketoisovalerate transaminase activity has been shown to be cotransducible with ilv gene cluster. The transaminase deficiency results in conditional isoleucine auxotrophy in the presence of alanine.

The product of the dye gene of Escherichia coli, mapping at 99-100 min, is required for expression of the sex factor F, and also appears to be involved in the regulation of envelope proteins. Mutation of dye thus results in loss of expression of the F-factor (Fex-), i.e. male sterility, and dye sens
A suppressor mutation of a temperature-sensitive mutant of ribosomal protein L24 (rplX19) was mapped close to the lon gene by genetic analysis and was shown to affect protease LA. The degradation and the synthesis rates of individual ribosomal proteins were determined. Proteins L24, L14, L15 and L27
