Plasmid transfer in Streptococcus faecalis: Production of multiple sex pheromones by recipients
(Elsevier, 1979-07)
In a previous report (1978, Proc. Nat. Acad. Sci. USA 75, 3479-3483), we showed that recipient strains of Streptococcus faecalis excrete a heat-stable substance (sex pheromone) which induces donor cells carrying certain ...
A possible role in the regulation of primary amination for a complex of glutamine: [alpha]-Ketoglutarate amidotransferase and glutamate dehydrogenase in
(Elsevier, 1972-07-11)
Both glutamine: [alpha]-ketoglutarate amidotransferase and glutamate dehydrogenase activities are obtained from grown in minimal medium containing glucose and ammonia. These activities are not additive, suggesting an ...
Escherichia coli gene transfer to unrelated bacteria by a histidine operon -- RP1 drug resistance plasmid complex
(Elsevier, 1974-07-10)
SummaryGenetic and physical evidence indicates that the Pseudomonas aeruginosa drug resistance factor, RP1, may promote the transfer of Escherichia coli histidine genes. The RP1 mobilized histidine genes are functionally ...
Plasmid-determined tetracycline resistance in Streptococcus faecalis: Tandemly repeated resistance determinants in amplified forms of pAM[alpha]1 DNA
(Elsevier, 1976-04-15)
We recently reported that the six-megadalton plasmid pAM[alpha]1 (one of two plasmids in Streptococcus faecalis strain DS-5C1) undergoes a gene amplification as a result of extended growth (many generations) of cells in ...
Feedforward inhibition in biosynthetic pathways: inhibition of the aminoacyl-tRNA synthetase by the penultimate product
(Elsevier, 1979-04-21)
Inhibition of the aminoacyl-tRNA synthetase by the penultimate product of a pathway for the biosynthesis of an amino acid has been reported for several pathways in many different types of organisms. A regulatory role for ...
Transient rates of synthesis of individual polypeptides in E. coli following temperature shifts
(Elsevier, 1978-03)
The effect of temperature shifts on the rates of synthesis of selected individual polypeptides in wild-type E. coli was studied through pulse-labeling and resolution of protein by the O'Farrell two-dimensional gel system.The ...
RNA dependent DNA synthesis in cell free preparations of human leukemia cells
(Elsevier, 1971-02-19)
A cell free preparation of human leukemic cells, grown in tissue culture, incorporated H3-thymidine phosphate into an acid insoluble product which was rendered acid soluble by the action of DNAase but not KOH or RNAase. ...
