Multifractal analysis of thermal denaturation based on the Peyrard-Bishop-Dauxois model.

Physical review. E, Statistical, nonlinear, and soft matter physics, 2011
The theory of DNA dynamics is exceedingly complex and not easily explained. In the past two decades, by adapting methods of statistical physics, the dynamics of DNA in contact with a thermal bath is widely studied. In this paper, the thermal denaturation

Effects of thermal denaturation on protein glycation

Life Sciences, 2002
Protein denaturation occurs at sites of inflammation. We hypothesized that denatured protein may provide a more susceptible target for glycation, which is a known mediator of inflammation. We examined the effects of thermal denaturation on the susceptibility of protein glycation using glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and aspartate ...

Analysis of the mechanism of lysozyme pressure denaturation from Raman spectroscopy investigations, and comparison with thermal denaturation.

Journal of Physical Chemistry B, 2011
Pressure denaturation of lysozyme dissolved in H(2)O and D(2)O was analyzed using Raman investigations in a wide frequency range. The simultaneous analysis of regions corresponding to the molecular fingerprint of the protein (500-1800 cm(-1)), and the ...

Chapter 8:Protein Thermal Denaturation Measurements via a Fluorescent Dye

, 2011
Protein thermal denaturation by following fluorescence of a reporter probe has developed into an important method to measure protein-ligand binding and characterize protein stability.

The thermal denaturation of chromatin core particles

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1984
The thermal denaturation of chicken erythrocyte core particles has been followed using changes in absorption and circular dichroism. The absorption-denaturation curve is biphasic, with transitions centred at 59 degrees C and 74 degrees C. The first of these transitions is reversible, whereas heating into the second transition produces irreversible ...

Immunochemical studies on thermal denaturation of ovomucoid

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1982
The thermal denaturation of ovomucoid was investigated by immunochemical methods, namely immunoprecipitation analyses and antibody-Sepharose 4B column chromatography. In the immunoprecipitation analyses, heated ovomucoid (90 degrees C, 90 min, pH 7.2) required about twice the antigen addition of the native protein to approach maximal precipitation with

Thermal denaturation and aggregation of egg proteins

Thermochimica Acta, 1992
Abstract The thermal denaturation of egg white and egg yolk proteins has been investigated by means of differential scanning calorimetry in natural, spontaneously aged samples. pH and protein content change with ageing. The overall endothermic signal from fresh egg white has been deconvoluted into three main gaussian components relevant to the ...

Thermal Processing of Biological Tissue at High Temperatures: Impact of Protein Denaturation and Water Loss on the Thermal Properties of Human and Porcine Liver in the Range 25–80 °C

, 2013
Biothermal engineering applications impose thermal excursions on tissues with an ensuing biological outcome (i.e., life or death) that is tied to the molecular state of water and protein in the system. The accuracy of heat transfer models used to predict

Thermal denaturation of beta-lactoglobulin and stabilization mechanism by trehalose analyzed from Raman spectroscopy investigations.

Journal of Physical Chemistry B, 2010
The thermal denaturation process of beta-lactoglobulin has been analyzed in the 20-100 degrees C temperature range by Raman spectroscopy experiments simultaneously performed in the region of amide modes (800-1800 cm(-1)) and in the low-frequency range ...

Thermal denaturation profiles and the structure of chromatin

Nature, 1976
Analysis of the melting profile of DNA stripped of non-histone proteins and histone H1 allows definite structural conclusions to be drawn; conversely, it is possible to calculate what a particular chromatin model's melting curve will look like.
