Photoreactivation of a cytoplasmic virus.
Ultraviolet light-inactivated frog virus 3 is efficiently photoreactivated by chick embryo cells. A cellular enzyme is presumably responsible for this repair of viral deoxyribonucleic acid, for the phenomenon is insensitive to an inhibitor of protein synthesis and is not seen in mammalian cells that are known to lack photoreactivating enzyme. Since frog virus 3 is a cytoplasmic virus, functiona...
متن کاملCharacteristics of the photoreactivation of pseudorabies virus.
Pfefferkorn, E. R. (Harvard Medical School, Boston, Mass.), Boyce W. Burge, and Helen M. Coady. Characteristics of the photoreactivation of pseudorabies virus. J. Bacteriol. 92:856-861. 1966.-Pseudorabies virus, killed with ultraviolet light and then allowed to adsorb to chick embryo tissue culture cells, can be photoreactivated by light of longer wavelengths. The photoreactivable sector is app...
متن کاملSusceptibility of three Eco-races of tropical Tasar silkworm to Antheraea mylitta cytoplasmic polyhedrosis virus (AmCPV)
Pathogenic infection in tasar silkworm, Antheraea mylitta Drury. is common and there is a breed specific response regarding tolerance. Observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds. Hence, the susceptibility of three eco-races of tasar silkworm viz. Daba, Sarihan and Raily to Antheraea mylitta Cytoplasmic Polyhedrosis Virus...
متن کاملPhotoreactivation in humans.
Photoreactivation is a DNA repair pathway that requires the presence of a photoreactivating enzyme, DNA photolyase. DNA photolyase recognizes and binds specifically to ultraviolet radiation (UVR)-induced cyclobutane pyrimidine dimers in DNA. Exposure of the photolyase-dimer complex to wavelengths in the range of 300-500 nm results, upon absorption of a photon, in the return of the dimerized pyr...
متن کاملPhotoreactivation in airborne Mycobacterium parafortuitum.
Photoreactivation was observed in airborne Mycobacterium parafortuitum exposed concurrently to UV radiation (254 nm) and visible light. Photoreactivation rates of airborne cells increased with increasing relative humidity (RH) and decreased with increasing UV dose. Under a constant UV dose with visible light absent, the UV inactivation rate of airborne M. parafortuitum cells decreased by a fact...
