DISORDER AND DENATURATION TRANSITION IN THE GENERALIZED POLAND-SCHERAGA MODEL [PDF]

, 2020
36 pages, 3 figuresInternational audienceWe investigate the generalized Poland-Scheraga model, which is used in the bio-physical literature to model the DNA denaturation transition, in the case where the two strands are allowed to be non-complementary ...

Single-molecule chemical denaturation of riboswitches [PDF]

, 2013
To date, single-molecule RNA science has been developed almost exclusively around the effect of metal ions as folding promoters and stabilizers of the RNA structure.

Enzyme activity below the dynamical transition at 220K [PDF]

, 1998
Enzyme activity requires the activation of anharmonic motions, such as jumps between potential energy wells. However, in general, the forms and time scales of the functionally important anharmonic dynamics coupled to motion along the reaction coordinate ...

The molecular basis of the effect of temperature on enzyme activity [PDF]

, 2010
Experimental data show that the effect of temperature on enzymes cannot be adequately explained in terms of a two-state model based on increases in activity and denaturation.

Honey-Induced Protein Stabilization as Studied by Fluorescein Isothiocyanate Fluorescence

The Scientific World Journal, 2013
Protein stabilizing potential of honey was studied on a model protein, bovine serum albumin (BSA), using extrinsic fluorescence of fluorescein isothiocyanate (FITC) as the probe.

Modulation of the Structure and Stability of Novel Camel Lens Alpha-Crystallin by pH and Thermal Stress

Gels, 2022
Alpha-crystallin protein performs structural and chaperone functions in the lens and comprises alphaA and alphaB subunits at a molar ratio of 3:1. The highly complex alpha-crystallin structure challenges structural biologists because of its large dynamic

Calorimetric and spectroscopic investigation of the unfolding of human apolipoprotein B.

Journal of Lipid Research, 1990
The unfolding of human apolipoprotein B-100 in its native lipid environment, low density lipoprotein (LDL), and in a soluble, lipid-free complex with sodium deoxycholate (NaDC) has been examined using differential scanning calorimetry (DSC) and near UV ...

Cryoprotective effect of trehalose and maltose on washed and frozen stored beef meat

Czech Journal of Food Sciences, 2011
The cryoprotective effects of trehalose and maltose (w = 2-10%) on washed beef meat were investigated. Washed beef meat produced from fresh beef meat was frozen and stored for 360 days at -30°C.

Calorimetric Study of Helix aspersa Maxima Hemocyanin Isoforms

Journal of Analytical Methods in Chemistry, 2018
The thermal unfolding of hemocyanin isoforms, β-HaH and αD+N-HaH, isolated from the hemolymph of garden snails Helix aspersa maxima, was studied by means of differential scanning calorimetry (DSC). One transition, with an apparent transition temperature (
