Isolation and partial characterization of a mutant of Escherichia coli deficient in DNA polymerase II.
A mutant of Escherichia coli deficient in DNA polymerase II has been isolated from E. coli polA1 by mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine and assay of polymerase activity in extracts of survivors. The polA1 mutation was suppressed during mutagenesis by introduction of the suppressor, su7(+), into the parental strain. The mutant, HMS83 polA1 polB1, contains less than 0.5% of the ...
متن کاملIsolation of a dihydrofolate reductase-deficient mutant of Escherichia coli.
A strain of Escherichia coli was isolated in which dihydrofolate reductase was not detected by an enzyme assay or by competition for antibody. This strain requires methionine, glycine, a purine, and thymidine for growth in addition to the auxotrophic requirements of the parent strain. It was found to be useful as a recipient of plasmids harboring dihydrofolate reductase genes.
متن کاملIsolation and Characterization of a New Peroxisome Deficient CHO Mutant Cell Belonging to Complementation Group 12
We searched for novel Chinese hamster ovary (CHO) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (PTS) of Pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (EGFP). From mutagenized TKaEG3(1–40) cells, the wild-type CHO-K1 stably expressing rat Pex2p and of rat Pex3p(1–40)-EGFP, numerous cell colonies resistant to...
متن کاملCharacterization of two membrane-associated glycolipids from an Escherichia coli mutant deficient in phosphatidylglycerol.
A temperature-sensitive mutant of Escherichia coli, deficient in phosphatidylglycerol at 42 “C, was previously isolated by means of a two-step mutagenesis (Nishijima, M., and Raetz, C. R. H. (1979) J. BioL Chem 254, 7837-7844). Under nonpermissive conditions, the membranes of this organism were found to accumulate two glycolipids, designated X and Y. We now report the isolation of these substan...
متن کاملEfficacy of trimethoprim in murine experimental infection with a thymidine kinase-deficient mutant of Escherichia coli.
The antimicrobial activity of trimethoprim is antagonized by thymidine in in vitro susceptibility tests. The purpose of this investigation was to determine whether this antagonism also occurred during experimental infection in mice, which have high serum thymidine concentrations. We derived a mutant strain of Escherichia coli, TT-48, incapable of utilizing exogenous thymidine from parent strain...
