folding of the interaction of histone hi with sodium n-dodecyl sulphate

Authors
abstract

the effects of sodium n-dodecyl sulphate (sds) on the structure of histone hi has been studied by a combination of e:quilibrium dialysis, u.v. spectroscopy ; polyacrylamide gel electrophoresis, protein titration and viscometery techniques using, 2.5 mm phosphate buffer, ph 6.4. the interaction of h, and sds in contrast tomanyothel-protein-sds interactions is organized between v 40 to 70. above v=40 there is an exothermic contribution from hi folding characterized by minima in the enthalpy curve at about 65 kj mol:' this subject has been confirmed by spectroscopy, electrophoresis , titrametery and viscometery techniques

The Unexpected Effect of Sodium Arsenate on the Interaction between Histone H1 and Sodium N-Dodecyl Sulphate

A Study was made on the interaction between histon H1 and sodium n-dodecyl sulphate (SDS) in the presence of sodium arsenate inside a phosphate buffer of pH 6.4, using spectroscopy and equilibrium dialysis at 27 °C. The binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the Wyman binding potential. The binding data hs been analysed...

Interaction Studies of Sodium N-Dodecyl Sulphate and Protons to Nistone H1

The relationship between the binding of sodium n-dodecyl sulphate and protons to histone H1 has been investigated by equilibrium dialysis and titrimetry. The data cover the pH range 3.2-10 and surfactant concentrations up to 3.0×10-3 mol dm-3. A theoretical approach based on the binding potential concept of Wyman is presented and has been used to make estima...
