Two routes for synthesis of phosphoenolpyruvate from C4-dicarboxylic acids in
(Elsevier, 1974-08-19)
Mutants of defective in both phosphoenolpyruvate carboxykinase and phosphoenolpyruvate synthetase are unable to use C4-dicarboxylic acids such as succinate and malate as carbon and energy sources for growth. Revertants ...
Benzoylarginine peptidase and iminopeptidase profiles of Treponema denticola strains isolated from the human periodontal pocket
(Springer-Verlag; Springer-Verlag New York Inc., 1986-03)
Seven clinical isolates and the ATCC strain 35405 of Treponema denticola , obtained from human periodontal pockets, were studied for peptidase activity with several chromogenic compounds as substrates. The cell sonicates ...
Checkpoints and restriction points in bacteria and eukaryotic cells
(Wiley Subscription Services, Inc., A Wiley Company, 2006-10)
Bacterial checkpoints, analogous to those proposed to exist in eukaryotic cells, offer insights into the definition of a checkpoint. Examination of bacterial “checkpoint” or arrest phenomena illustrate problems with a ...
Effects of rifampicin, streptolydigin and actinomycin D on the replication of Col E1 plasmid DNA in Escherichia coli
(Elsevier, 1973-04-15)
We recently reported (Clewell et al., 1972) on an inhibitory effect of rifampicin on Col E1 plasmid replication. The present study represents a further characterization of this phenomenon as well as a study of the effects ...
Amino acid sequence of pheromone-inducible surface protein in Enterococcus faecalis, that is encoded on the conjugative plasmid pPD1
(Elsevier, 1990-07-02)
The major pheromone-inducible protein, PD78, believed to contribute to bacterial conjugation, was purified from Enterococcus (formerly Streptococcus) faecalis cells containing the plasmid pPD1. A cloned EcoRI-Bg/II 3.6-kbp ...
[lambda] N antitermination system: Functional analysis of phage interactions with the host NusA protein
(Elsevier, 1987-04-20)
Coliphage [lambda] gene expression is regulated temporally by systems of termination and antitermination of transcription. The [lambda]-encoded N protein (pN) acting with host factors (Nus) at sites (nut) located downstream ...
Isolation and structure of the Streptococcus faecalis sex pheromone, cAM373
(Elsevier, 1986-09-29)
The Streptococcus faecalis sex pheromone, cAM373, which induces a mating response of donor cells harboring plasmid pAM373 and is also produced by Staphylococcus aureus, was isolated and its structure determined. Supernatant ...
Identification and characterization of the cAMP binding proteins of yeast by photoaffinity labeling
(Elsevier, 1979-10-12)
Contrary to previous reports, we find the molecular weight of the major cAMP-binding protein in to be 54,000 daltons. A number of lower molecular weight proteins have also been identified and are believed to be breakdown ...
Bacteriophage Lambda N-Dependent Transcription Antitermination : Competition for an RNA Site May Regulate Antitermination
(Elsevier, 1994-02-10)
Bacteriophage [lambda] controls the expression of its early genes in a temporal manner by a series of transcription termination and antitermination events. This antitermination requires the [lambda] N protein as well as ...
Temperature dependent alteration in bacterial protein composition
(Elsevier, 1975-02-03)
When different strains of or are grown at 30[deg] or at 42[deg] and their proteins are compared using SDS-polyacrylamide gel electrophoresis, differences are observed in the protein composition of the cells. In particular, ...
