abstract = {<jats:p>Biomolecular condensates often form through the self-assembly of disordered proteins with low-complexity sequences. In these polypeptides, the aromatic amino acids phenylalanine and tyrosine act as key ‘sticker’ residues, driving the cohesion of dense phases. Recent studies on condensates suggest a hierarchy in sticker strength, with tyrosine being more adhesive than phenylalanine. This hierarchy aligns with experimental data on amino acids solubilities and potentials of mean force derived from atomistic simulations. However, it contradicts conventional chemical intuition based on hydrophobicity scales and pairwise contact statistics from experimental structures of proteins, which suggest that phenylalanine should be the stronger sticker. In this work, we use molecular dynamics simulations and quantum chemistry calculations to resolve this apparent discrepancy. Using simple model peptides and side-chain analogues, we demonstrate that the experimentally observed hierarchy arises from the lower free energy of transfer of tyrosine into the condensate, mediated by both stronger protein-protein interactions and solvation effects in the condensate environment. Notably, as the dielectric constant of the media surrounding the stickers approaches that of an apolar solvent, the trend reverses, and phenylalanine becomes the stronger sticker. These findings highlight the role of the chemical environment in modulating protein-protein interactions, providing a clear explanation for the crossover in sticker strength between tyrosine and phenylalanine in different media.</jats:p>},

abstract = {<jats:p>The current status of the theoretical foundations of the Chiral-Induced Spin Selectivity (CISS) effect has substantially improved from its original one-electron formulation. However, there is a need to improve the inclusion of electron–vibrational interaction, the exchange and correlation effects arising from electron–electron interactions, and non-Born–Oppenheimer coupling to enhance the predictive power of the theory and its agreement with experiments. In an attempt to overcome these difficulties, we advance in the present work a microscopic quantum mechanical treatment of CISS based on the relativistic Breit–Pauli many-particle Hamiltonian. In particular, we determine in this context the effect that including non-Born–Oppenheimer components arising in a Taylor expansion of the electron–nuclear potential has on the spin–orbit coupling term of this Hamiltonian. We also consider in this framework the electron–electron exchange and correlation effects and propose some practical approximations based on non-relativistic approaches. Finally, we extend the application of the Breit–Pauli Hamiltonian to describe nuclear–nuclear spin interactions and discuss the possibility of explaining enantiomeric selectivity in cross-polarization nuclear magnetic resonance experiments.</jats:p>},

abstract = {Economical multireference (MR) diagnostics are essential for high-throughput computational studies, enabling the rapid and accurate identification of molecules affected by nondynamic correlation within large molecular datasets. Although various MR diagnostics have been proposed, benchmarking studies that help identify the criteria for an effective diagnostic are still scarce. In this article, we examine a wide range of correlation measures to evaluate their potential as MR diagnostics. We identify a small set of valid size-intensive correlation measures based on maximum metrics, exhibiting similar predictive values. Among these, we highlight INDmax, which offers an easy interpretation: it captures the largest deviation of a natural orbital occupancy from the boundary values corresponding to a single-reference wave function. No energy-based correlation measure was found suitable for constructing MR diagnostics. Finally, we demonstrate how average correlation measures, although not suitable as MR diagnostics, can provide a more comprehensive view of electron correlation within the molecule.},
