A new gene, fdaB, has been mapped by transduction and partial diploid analyses and is located adjacent to argA at 59.9 min on the Escherichia coli recalibrated linkage map. This gene is involved in expression of fructose-1, 6-diphosphate aldolase activity and indirectly in ribosomal RNA synthesis. The temperature-sensitive mutant strain AA-157, containing the defective gene product of fdaB, accumulates high concentrations of fructose 1, 6-diphosphate at the nonpermissive temperature.

ABSTRACT We isolated a temperature-sensitive mutant with a mutation in mviN, an essential gene in Escherichia coli. At the nonpermissive temperature, mviN mutant cells swelled and burst. An intermediate in murein synthesis, polyprenyl diphosphate-N-acetylmuramic acid-(pentapeptide)-N-acetyl-glucosamine, accumulated in mutant cells. These results indicated that MviN is involved in murein synthesis.

Temperature Sensitive Mutant

An assembly negative temperature-sensitive mutant of Ad2, ts48 was shown to exert dominance over other ts mutants and wild-type virus during coinfection, by inhibiting virion assembly. Dominance was only expressed at the nonpermissive temperature.
