[Interaction between Pseudomonas aeruginosa phages-transposons: genetic analysis of the trait of inhibition by prophage D3112 of phage B39 development]. 1996

V A Gerasimov, and A S Ianenko, and V Z Akhverdian, and V N Krylov

A novel, previously unknown cip gene of Pseudomonas aeruginosa phage D3112 was discovered. The cip gene is responsible for inhibiting the intracellular growth of the related heteroimmune phage B39 of P. aeruginosa. It was shown that the cip gene product inhibits replication of the B39 genome, interacting, apparently, with the definite s+ site in the phage B39 genome. Mutants cip- of phage D3112, incapable of inhibiting the growth of phage B39, and B39 mutants, insensitive to the action of the cip gene product of phage D3112, were isolated.

UI MeSH Term Description Entries
D008242 Lysogeny The phenomenon by which a temperate phage incorporates itself into the DNA of a bacterial host, establishing a kind of symbiotic relation between PROPHAGE and bacterium which results in the perpetuation of the prophage in all the descendants of the bacterium. Upon induction (VIRUS ACTIVATION) by various agents, such as ultraviolet radiation, the phage is released, which then becomes virulent and lyses the bacterium. Integration, Prophage,Prophage Integration,Integrations, Prophage,Prophage Integrations
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D004251 DNA Transposable Elements Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.

D014775 Virus Activation The mechanism by which latent viruses, such as genetically transmitted tumor viruses (PROVIRUSES) or PROPHAGES of lysogenic bacteria, are induced to replicate and then released as infectious viruses. It may be effected by various endogenous and exogenous stimuli, including B-cell LIPOPOLYSACCHARIDES, glucocorticoid hormones, halogenated pyrimidines, IONIZING RADIATION, ultraviolet light, and superinfecting viruses.
