Plasmids comprising transgene insertions in four lines of transgenic mice have been retrieved by plasmid rescue into a set of Escherichia coli strains with mutations in different members of the...
Introduction of bacteriophage lambda into cells of Klebsiella aerogenes.
We have shown that a mutation in the cro gene of phage lambda greatly reduces zygotic induction. This observation has allowed us to move this phage on an episome into cells of Klebsiella aerogenes...
Deletion mapping of the polA-metB region of the Escherichia coli chromosome.
Pahel, G, Bloom, F R, Tyler, B
A lambdacI857 prophage inserted into one of the genes of the rha locus was used to select deletions unambiguously ordering the markers polA-glnA-rha-pfkA-tpi-metBJF. Transduction with phage P1...
Bloom, F R, Levin, M S, Foor, F, Tyler, B
A lambda phage (lambdaNK55) carrying the translocatable element Tn10, conferring tetracycline resistance (Tetr), has been utilized to isolate glutamine auxotrophs of Escherichia coli K-12. Such...
Regulation of histidase synthesis in intergeneric hybrids of enteric bacteria.
Goldberg, R B, Bloom, F R, Magasanik, B
Regulation of the expression of the histidase coded by hutk of Klebsiella aerogenes in Salmonella typhimurium and in Escherichia coli and of the expression of the histidase coded by huts of S....
Bloom, F R, Streicher, S L, Tyler, B
In Klebsiella aerogenes but not in Salmonella typhimurium glutamine synthetase can function during nitrogen-limited growth to increase the rate of synthesis of histidase from the hut genes of S....
Mutants constitutive for D-serine deaminase (Dsdase) synthesis were isolated by utilizing D-serine as sole nitrogen or carbon source in the chemostat. This method generated only regulatory...
Two classes of D-serine deaminase (Dsdase)-specific secondary mutants of Escherichia coli K-12 were isolated from a Dsdase low constitutive nonhyperinducible mutant as types which could grow in the...
Positive control in the D-serine deaminase system of Escherichia coli K-12.
Bloom, F R, McFall, E, Young, M C, Carothers, A M
Two new types of D-serine deaminase (Dsdase)-negative mutants have been isolated and characterized. The first fails to synthesize a functional dsdC gene product as a result of dsdC- (regulator...
