The finite size effects and the two-state paradigm of protein folding
Artem Badasyan, Matjaz Valant, Joze Grdadolnik +1
The coil to globule transition of the polypeptide chain is the physical phenomenon behind the folding of globular proteins. Globular proteins with a single domain usually consist o…
Solvent Effects in the Helix-Coil Transition Model can explain the Unusual Biophysics of Intrinsically Disordered Proteins
Artem Badasyan, Yevgeni Sh. Mamasakhlisov, Rudolf Podgornik +1
We analyze a model statistical description of the polypeptide chain helix-coil transition, where we take into account the specificity of its primary sequence, as quantified by the…
A unified description of solvent effects in the helix-coil transition
Artem Badasyan, Shushanik A. Tonoyan, Achille Giacometti +4
We analyze the problem of the helix-coil transition in explicit solvents analytically by using spin-based models incorporating two different mechanisms of solvent action: explicit…
Osmotic pressure induced coupling between cooperativity and stability of a helix-coil transition
Artem Badasyan, Shushanik Tonoyan, Achille Giacometti +4
Most helix-coil transition theories can be characterized by a set of three parameters: energetic, describing the (free) energy cost of forming a helical state in one repeating unit…
Stacking and Hydrogen Bonding. DNA Cooperativity at Melting
Vladimir F. Morozov, Artem V. Badasyan, Arsen V. Grigoryan +2
By taking into account base-base stacking interactions we improve the Generalized Model of Polypeptide Chain (GMPC). Based on a one-dimensional Potts-like model with many-particle…
Helix-coil Transition in Closed Circular DNA
V. F. Morozov, Shura Hayryan, E. Sh. Mamasakhlisov +3
A simplified model for the closed circular DNA (ccDNA) is proposed to describe some specific features of the helix-coil transition in such molecule. The Hamiltonian of ccDNA is rel…
