Singularities in Molecular Conformation
The intramolecular coupling between molecular groups leads to singularities in the molecular conformation, acting like a switch in a molecular-scale rotor. This, in turn, affects the potential-energy (Ep) barriers, acquiring a sharp shape originating from superimposed Ep functions of the molecular conformers with differently coupled methyl groups.

EC-Conf: A ultra-fast diffusion model for molecular conformation generation with equivariant consistency. [PDF]
Despite recent advancement in 3D molecule conformation generation driven by diffusion models, its high computational cost in iterative diffusion/denoising process limits its application.

Auto-Encoding Molecular Conformations
In this work we introduce an Autoencoder for molecular conformations. Our proposed model converts the discrete spatial arrangements of atoms in a given molecular graph (conformation) into and from a continuous fixed-sized latent representation. We demonstrate that in this latent representation, similar conformations cluster together while distinct ...

CONFORMATIONAL TRANSITIONS IN MOLECULAR SYSTEMS [PDF]
Proteins are the "work horses" in biological systems. In almost all functions specific proteins are involved. They control molecular transport processes, stabilize the cell structure, enzymatically catalyze chemical reactions; others act as molecular motors in the complex machinery of molecular synthetization processes.

Direct Molecular Conformation Generation
Molecular conformation generation aims to generate three-dimensional coordinates of all the atoms in a molecule and is an important task in bioinformatics and pharmacology. Previous methods usually first predict the interatomic distances, the gradients of interatomic distances or the local structures (e.g., torsion angles) of a molecule, and then ...
