The Ultraviolet Light and Photosensitized Inactivation of Tobacco Mosaic Virus
The quantum yield for the inactivation of tobacco mosaic virus has been determined at 253.7 mmicro and found to be 4.3 x 10(-6). The possible significance of the observed one-hit process of inactivation has been discussed in terms of the kinetics and the rupture of model substances including nucleic acid. The ultraviolet light inactivation, which proceeds independent of oxygen, occurs without c...
متن کاملDeposition of platinum clusters on surface-modified Tobacco mosaic virus.
Nanoscaled Pt conductors were prepared from genetically engineered Tobacco mosaic virus (TMV) templates through Pt cluster deposition on the outer surface of the TMV. Pt clusters were synthesized and deposited on the engineered TMV with surface-exposed cysteine via the in situ mineralization of hexachloroplatinate anions. This deposition was driven by the specific binding between thiols and the...
متن کاملQuantum yields for inactivation of tobacco mosaic virus nucleic acid by ultraviolet radiation (254 nm.).
The quantum yield, under non-photoreactivating conditions, for inactivation of tobacco mosaic virus RNA by ultraviolet radiation (254 nm.) is independent of the RNA concentration but varies appreciably with the ionic strength of the irradiation solvent, being approximately three times greater in water than in o-I M-potassium phosphate buffer. Photoreactivation of inactivated tobacco mosaic viru...
متن کاملInfection of tobacco mesophyll protoplasts by tobacco mosaic virus.
It was proved that the protoplasts prepared from mesophyll of Nicotiana tabacum are infected by tobacco mosaic virus. The infection occurred when purified tobacco mosaic virus particles were added to a protoplast suspension in the presence of poly-L-ornithine. The virus multiplied in these protoplasts to a level of 10(6) virus particles per infected protoplast during 24 hours of incubation. The...
متن کاملOxidation of tyrosine by permanganate in presence of cetyltrimethylammonium bromide.
In this paper we report the effect of cetyltrimethylammonium bromide, CTAB on the oxidative degradation of tyrosine by permanganate. The reaction rate bears a first-order dependence on the [MnO(4)(-)] under pseudo-first-order conditions (large excess of [tyrosine] for at least 10 times over [MnO(4)(-)]) in presence of 10.0x10(-4)moldm(-3) CTAB. The effect of total [CTAB] on the reaction rate wa...
