The denaturation transition of DNA in mixed solvents. [PDF]

open access: yesBiophys J, 2006
The helix-to-coil denaturation transition in DNA has been investigated in mixed solvents at high concentration using ultraviolet light absorption spectroscopy and small-angle neutron scattering. Two solvents have been used: water and ethylene glycol. The "melting" transition temperature was found to be 94 degrees C for 4% mass fraction DNA/d-water and ...

Poland–Scheraga Models and the DNA Denaturation Transition [PDF]

open access: yesJournal of Statistical Physics, 2004
Poland-Scheraga models were introduced to describe the DNA denaturation transition. We give a rigorous and refined discussion of a family of these models. We derive possible scaling functions in the neighborhood of the phase transition point and review common examples.

Why is the DNA Denaturation Transition First Order? [PDF]

open access: yesPhysical Review Letters, 2000
We study a model for the denaturation transition of DNA in which the molecules are considered as composed of a sequence of alternating bound segments and denaturated loops. We take into account the excluded-volume interactions between denaturated loops and the rest of the chain by exploiting recent results on scaling properties of polymer networks of ...

Water mobility, denaturation and the glass transition in proteins

open access: yesBiochimica Et Biophysica Acta - Proteins and Proteomics, 2012
A quantitative mechanism is presented that links protein denaturation and the protein-water glass transition through an energy criterion for the onset of mobility of strong protein-water bonds. Differences in the zero point vibrational energy in the ordered and disordered bonded states allow direct prediction of the two transition temperatures.

Investigation of DNA denaturation from generalized Morse potential

open access: yesMaterials and Devices, 2018
In this paper, we present a non-linear model for the study of DNA denaturation transition. To this end, we assume that the double-strands DNA interact via a realistic generalized Morse potential that reproduces well the features of the real ...

A DSC study of zinc binding to bovine serum albumin (BSA) [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
The thermal denaturation of bovine serum albumin (BSA) is a kinetically and thermodynamically controlled process. The effects of zinc binding to bovine serum albumin (BSA), followed by differential scanning calorimetry (DSC), were investigated in this ...

Highly anomalous energetics of protein cold denaturation linked to folding-unfolding kinetics. [PDF]

open access: yesPLoS ONE, 2011
Despite several careful experimental analyses, it is not yet clear whether protein cold-denaturation is just a "mirror image" of heat denaturation or whether it shows unique structural and energetic features. Here we report that, for a well-characterized

Irreversible denaturation of maltodextrin glucosidase studied by differential scanning calorimetry, circular dichroism, and turbidity measurements. [PDF]

open access: yesPLoS ONE, 2014
Thermal denaturation of Escherichia coli maltodextrin glucosidase was studied by differential scanning calorimetry, circular dichroism (230 nm), and UV-absorption measurements (340 nm), which were respectively used to monitor heat absorption ...
