Protein materials are rapidly gaining interest in materials sciences and nanomedicine because of their intrinsic biocompatibility and full biodegradability. The controlled construction of supramolecular entities relies on the controlled oligomerization of individual polypeptides, achievable through different strategies. [...]

We report quantum mechanical/molecular mechanical non-adiabatic molecular dynamics simulations on the electronically excited state of green fluorescent protein mutant S65T/H148D. We examine the driving force of the ultrafast (τ < 50 fs) excited-state proton transfer unleashed by absorption in the A band at 415 nm and propose an atomistic description of the two dynamical regimes experimentally observed [Stoner Ma et al. [...]

Conditionally disordered proteins are either ordered or disordered depending on the environmental context. The substrates of the mitochondrial intermembrane space (IMS) oxidoreductase Mia40 are synthesized on cytosolic ribosomes and diffuse as intrinsically disordered proteins to the IMS, where they fold into their functional conformations; behaving thus as conditionally disordered proteins.

Background: An increasing number of proteins are being shown to assemble into amyloid structures that lead to pathological states. Among them, mammalian prions outstand due to their ability to transmit the pathogenic conformation, becoming thus infectious. [...]

7 p, 899.7 KB Common features in the unfolding and misfolding of PDZ domains and beyond : the modulatory effect of domain swapping and extra-elements / Murciano Calles, Javier (Universidad de Granada. Departamento de Química Física) ; Güell Bosch, Jofre (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular) ; Villegas Hernández, Sandra (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular) ; Martínez, José C. (Universidad de Granada. Departamento de Química Física)
PDZ domains are protein-protein interaction modules sharing the same structural arrangement. To discern whether they display common features in their unfolding/misfolding behaviour we have analyzed in this work the unfolding thermodynamics, together with the misfolding kinetics, of the PDZ fold using three archetypical examples: the second and third PDZ domains of the PSD95 protein and the Erbin PDZ domain.
