Binding of ethidium bromide causes dissociation of the nucleosome core particle.
نویسندگان
چکیده
The binding of ethidium bromide to chicken erythrocyte core particles results in a step-wise dissociation of the structure that involves the initial release of one copy each of histones H2A and H2B. Quantitation of the dissociated DNA reveals that a critical amount of drug is required for the dissociation. Above the critical value, the dissociation is time dependent, reversible, and independent of DNA concentration.

Binding of polylysine and ethidium bromide to nucleosomal DNA: comparison of biochemical and electron microscopical results.
Ethidium bromide and polylysine interact with nucleosomal DNA and lead to change of biochemical properties and to morphological changes as to the distance between the two core particles of a nucleosome dimer. With increasing polylysine concentration, the buoyant density of nucleosomes decrease and the accessibility of the nucleosomal DNA to micrococcal nuclease is lowered. Electron microscopy o...

In this research, the interaction of hexadecyl trimahyl ammonium bromide (HTAB) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. The obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as Wyman binding pote...
متن کاملThe metastable state of nucleocapsids of enveloped viruses as probed by high hydrostatic pressure.
Enveloped viruses fuse their membranes with cellular membranes to transfer their genomes into cells at the beginning of infection. What is not clear, however, is the role of the envelope (lipid bilayer and glycoproteins) in the stability of the viral particle. To address this question, we compared the stability between enveloped and nucleocapsid particles of the alphavirus Mayaro using hydrosta...
متن کاملThe Effect of NO System on Ethidium Bromide-Induced Oxidative Stress in the Hippocampal Formation of Male Rats
Background Acute and chronic effects of nitric oxide on oxidative stress and neuronal demyelination have been reported in human and animal models. Objective Oxidative stress is involved in the pathogenesis of demyelinated animals; thus, this study investigated the effects of nitric oxide system and ethidium bromide on oxidative stress in the hippocampal formation. Methods This experimental...
متن کاملBinding of cis- and trans-dichlorodiammineplatinum(II) to the nucleosome core.
The binding of the antitumor drug cis-dichlorodiammineplatinum(II) and its inactive trans isomer with the nucleosome core particle has been investigated. Kinetic studies show that platinum binding increases with incubation time, from a few bound platinum atoms per nucleosome core in the first 0.5 hr to 40-50 after 40 hr. There is no crosslinking or dissociation of nucleosome cores upon platinum...
