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 ...
Streptococcus faecalis sex pheromone (cAD1) response: Evidence that the peptide inhibitor excreted by pAD1-containing cells may be plasmid determined
(Elsevier, 1987-01)
Streptococcus faecalis strains harboring the conjugative plasmid pAD1 excrete a small peptide, iAD1, which inhibits the sex pheromone cAD1. Studies making use of the host strain Streptococcus faecium 9790, which normally ...
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 ...
Tn917 transposase. Sequence correction reveals a single open reading frame corresponding to the tnpA determinant of Tn3-family elements
(Elsevier, 1991-03)
A nucleotide sequence correction on the Enterococcus faecalis transposon Tn917 indicates that what was formerly thought to be two open reading frames (ORF5 and ORF6) is actually one reading frame (ORF5). The latter exhibits ...
int-h: an int mutation of phage [lambda] that enhances site-specific recombination
(Elsevier, 1980-07)
The mutation int-h3 maps in the int gene of coliphage [lambda] and results in the synthesis of an integrase with enhanced activity, which is manifested by an ability to support [lambda] site-specific recombination relatively ...
mnd2: A New Mouse Model of Inherited Motor Neuron Disease
(Elsevier, 1993-06)
The autosomal recessive mutation mnd2 results in early onset motor neuron disease with rapidly progressive paralysis, severe muscle wasting, regression of thymus and spleen, and death before 40 days of age. mnd2 has been ...
Sex pheromones and plasmid transfer in Enterococcus faecalis
(Elsevier, 1989-05)
Plasmid-free Enterococcus faecalis excrete peptides (sex pheromones) which specifically induce a mating response in strains harboring certain conjugative plasmids. The response is characterized by the synthesis of a "fuzzy" ...
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 ...
