Some Effects of Iodine and Other Reagents on the Structure and Activity of Tobacco Mosaic Virus
1. Denatured tobacco mosaic virus has a number of SH groups corresponding to its total sulfur content of 0.2 per cent. The SH groups were estimated by titration with ferricyanide, tetrathionate, and p-chloromercuribenzoate in guanidine hydrochloride solution and by reduction of the uric acid reagent in urea solution. 2. The SH groups of tobacco mosaic virus or their precursors can be abolished ...
متن کاملThe isoelectric points of some strains of tobacco mosaic virus.
The detailed amino acid analysis of several strains of tobacco mosaic virus carried out by Knight (1) has revealed interesting chemical similarities and differences among these strains, although they are morphologically very similar (2). In the present work the isoelectric points of the strains which Knight has analyzed were determined by a method developed by the author (3). The virus strains ...

متن کاملThe nucleic acids of some strains of tobacco mosaic virus.
Investigation of the protein compositions of highly purified preparation8 of eight strains of tobacco mosaic virus revealed that each strain possesses a characteristic composition which in several instances could be demonstrated to differ significantly from that of the other strains (1). The differences found consist mainly of altered proportions of certain amino acids, but it was also found th...
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...
