Denaturation Transition of Stretched DNA [PDF]
Physical Review Letters, 2008 We generalize the Poland-Scheraga model to consider DNA denaturation in the presence of an external stretching force. We demonstrate the existence of a force-induced DNA denaturation transition and obtain the temperature-force phase diagram.

Entropy-driven denaturation enables sustainable protein regeneration through rapid gel-solid transition [PDF]
Nature CommunicationsThe upcycling of protein materials has long been hindered by the difficulty in restructuring them to usable forms. In contrast to proteins extracted using conventional organic denaturants, keratin treated with concentrated inorganic lithium bromide (LiBr)

Why is the DNA Denaturation Transition First Order?
Physical 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.

Investigation of DNA denaturation from generalized Morse potential
Materials 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]
Journal 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]
PLoS 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]
PLoS 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 ...

DNA-binding function of c-Myb R2R3 around thermal denaturation temperature
Biophysics and Physicobiology, 2021 The minimum DNA-binding domain of the transcriptional factor c-Myb R2R3 remarkably fluctuates in the solution. In the present study, we evaluated the protein fluctuation of R2R3 C130I mutant, R2R3*, on its DNA-binding and folding thermodynamics.

The regulatory subunit of PKA-I remains partially structured and undergoes β-aggregation upon thermal denaturation. [PDF]
PLoS ONE, 2011 BackgroundThe regulatory subunit (R) of cAMP-dependent protein kinase (PKA) is a modular flexible protein that responds with large conformational changes to the binding of the effector cAMP.
