On the nucleoproteins of avian tubercle bacilli.
The nucleic acids of tubercle bacilli have formed the subject of several studies, among which may be mentioned those by Ruppel (l), Levene (2), and Johnson and his associates (3-5). The work of Mensel and Heidelberger (6) on the fractionation of the proteins of the tubercle bacillus revealed the presence of several protein fractions, rich in phosphorus and in purines, which appeared to be nucle...
متن کاملStudies on nucleoproteins. III. Deoxyribonucleic acid complexes with basic polyelectrolytes and their fractional extraction.
The fractionation of deoxypentose nucleic acids, recently reported from this laboratory (1, 2), is essentially based on the fractional extraction of nucleohistone or artificial histone nucleates with salt solutions of increasing concentration in the presence of a chloroform phase. In this manner, a series of fractions of regularly graded composition (falling proportions of guanine and cytosine,...
متن کاملNucleoproteins and Gene Structure *
It is generally recognized that the genes or inheritable characters of all organisms, with the possible exception of the bacteria, are localized in the cell nucleus, and, more specifically, in the chromosomes. The intrinsic relationship between the genes and the chromosomal nucleoproteins is supported by cytochemical as well as by photochemical evidence: Desoxyribonucleoproteins represent the q...
متن کاملGenome encapsidation by orthobunyavirus nucleoproteins.
All negative-sense, single-stranded RNA (−ssRNA) viruses encode a nucleoprotein (NP), the major function of which is to bind viral RNAs and encapsidate them as ribonucleoprotein complexes (RNPs) (1, 2). Consequently, the genomes of −ssRNA viruses do not exist as naked RNA but rather as protein–RNA complexes with high-order structures. In PNAS, Li et al. (3), Niu et al. (4), and Reguera et al. (...
متن کاملEffects of Puromycin on the Nucleoproteins of the Hela Cell
The effects of several concentrations of puromycin on the nucleoproteins of HeLa cells grown in monolayers were studied by cytochemical and biochemical techniques. The earliest change at all concentrations of puromycin was a decrease in a granular form of ribonucleoprotein (RNP) that is demonstrable in the normal HeLa cell by the toluidine blue-molybdate (TBM) stain. The other types of RNP reve...
