Special Issue Information

Dear Colleagues,

Dynamics in biomolecules play an essential role in various biological processes such as enzymatic reactions, protein folding, and molecular recognition. Dynamics study in biomolecules combines computational modeling, experimental techniques, and theoretical approaches to enhance our understanding of the intricate workings of life at a molecular level. As a computational technique for studying biomolecular dynamics, molecular dynamics (MD) simulation applies principles of classical physics to simulate the motions and interactions of atoms in a biomolecule over time. With the recent success of artificial intelligence (AI) in protein structure prediction, the potential of AI to revolutionize the study of biomolecular dynamics with MD simulations has been demonstrated in many recent publications. We expect that, in the future, AI will be integrated in unexpected and smart ways into the various aspects (such as force field, propagation algorithm, sampling, and analysis) of dynamic study on biomolecules with MD simulations and expand dramatically the applicability of MD simulations in biomolecular systems.

We look forward to collecting research reporting advances in the AI-enhanced study of biomolecular dynamics with MD simulations. Topics of interest include but are not limited to the following general areas.

AI-based force field;

AI-based propagation algorithm;

AI-enhanced sampling algorithm;

AI-enhanced analysis approach;

Enzymatic reactions;

RNA structure and dynamics;

Protein–nucleic acid complexes;

Protein–ligand complexes;

Protein–membrane systems;

Protein–protein complexes.

Roseolumiflavin is a deep red microcrystalline derivative of isoalloxazine that exhibits a weak photophysical activity in the solid state. In aqueous as well as in acidic solution of formic or acetic acid, respectively, it tends to form solvates. Herein, we present a set of binary and ternary roseolumiflavin solvates including one hydrate and a solvate hydrate. The impact of the solvent on solvate formation along with an in-depth structural analysis was investigated. Calculations of the lattice energies provide insight into the phase stability of the evaluated systems showing an energetic benefit for all solvates with values up to −395.82 kJ/mol. The total interaction energies between molecules calculated via Crystal Explorer further identified cofacial π···π stacks to be the most strongly bonding fragments in the crystal lattices for all systems except the formic acid solvate, followed by remarkably weaker hydrogen-bonded arrangements. The energetic contributions of single intermolecular interactions within the fragments are evaluated by an atoms-in-molecules approach. It is shown that physicochemical properties, such as thermal stability, can be tuned depending on the incorporated solvent molecules despite a high decomposition temperature of the chromophore.
