Histone Hi deposition and histone - DNA interactions in replicating chromatin ( chromatin replication / histone - DNA crosslinking /
An immunochemical method for analyzing protein interactions with BrdUrd-substituted DNA was used to study binding of histones to nascent DNA in nuclei. The results indicate that in Ehrlich ascites tumor (EAT) cells, histone Hi deposits on newly replicated DNA simultaneously with or immediately after core histone deposition so that in chromatin replicated for 3 min, the stoichiometry of the hist...
متن کاملTissue-specific chromosomal non-histone protein interactions with DNA.
A group of chromosomal non-histone proteins with affinity for DNA (NP) was isolated from rat liver and Novikoff hepatoma. This fraction, which represents less than 5% of the total chromatin protein content, binds preferentially to unique, double-stranded sequences of fractionated homologous DNA. The interactions are strong at low ionic strength (Km = 6.7 X 10(-9) M) and decrease with rising sal...
متن کاملLinker Histone / DNA Interactions : In Vitro Studies
approved: Jordanka Zlatanova By studying the linker histone/DNA complex in vitro, our goal was to gain further insight into the interaction of these histones in chromatin structure, which, in turn, helps us in better understanding critical biological processes such as replication, transcription, and recombination. In direct competition experiments, we have confirmed previous results of the pref...
متن کاملNature of Lithium Interactions with DNA Nucleobases: Theoretical Study
In the present study, the interactions of three different lithium species Li+, Li3+ and CH3Li with several different sites of the most stable tautomers of DNA nucleo-bases are presented. This investigation is based on the results of thermochemical properties, Quantum Theory of Atoms in Molecules (QTAIM) and Natural Bond Orbi...
متن کاملProkaryote clustering based on DNA curvature distributions
Massive determination of complete genome sequences has led to the development of different tools for genome comparisons. Our approach is to compare genomes according to typical genomic distributions of a mathematical function that reflects a certain biological function. In this study we used comprehensive genome analysis of DNA curvature distributions in coding and non-coding regions of prokary...
