Phase variation in tcpH modulates expression of the ToxR regulon in Vibrio cholerae
(Blackwell Science Ltd, 1997-09)
Regulation of DNA synthesis in bacteria: analysis of the Bates/Kleckner licensing/initiation-mass model for cell cycle control
(Blackwell Publishing Ltd, 2006-10)
Bates and Kleckner have recently proposed that bacterial cell division is a licensing agent for a subsequent initiation of DNA replication. They also propose that initiation mass for DNA replication is not constant. These ...
Identification and characterization of genes encoding sex pheromone cAM373 activity in Enterococcus faecalis and Staphylococcus aureus
(Blackwell Science Ltd., 2002-05)
The sex pheromone cAM373 of Enterococcus faecalis and the related staph -cAM373 of Staphylococcus aureus were found to correspond to heptapeptides located within the C-termini of the signal sequences of putative prelipoproteins. ...
Enterococcus faecalis conjugative plasmid pAM373: complete nucleotide sequence and genetic analyses of sex pheromone response
(Blackwell Science Ltd, 2000-09)
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 ...
Evidence for the utilization of host tRNA(m5 U)methylase to modify tRNA coded by phage T4
(Elsevier, 1973-04)
Mutants of Escherichia coli defective only in the biosynthesis of 5-methyluridine (ribothymidine) in their transfer ribonucleic acid (tRNA) were employed to investigate whether phage T4 induces its own tRNA (m5U)methylase ...
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" ...
Co-ordination of Legionella pneumophila virulence with entry into stationary phase by ppGpp
(Blackwell Science Ltd, 1999-08)
Design principles for elementary gene circuits: Elements, methods, and examples
(The American Institute of Physics, 2001-03)
The control of gene expression involves complex circuits that exhibit enormous variation in design. For years the most convenient explanation for these variations was historical accident. According to this view, evolution ...
