摘要:

As the Nobel Prize in Chemistry 2024 was awarded to protein structure prediction and protein design, how to leverage artificial intelligence (AI) to accurately characterize the dynamic motions of proteins is yet another challenge to be tackled. We introduce an AI powered ab initio biomolecular dynamics system (AI2BMD) that can efficiently simulate full-atom large biomolecules with ab initio accuracy and was recently published on Nature. AI2BMD uses a protein fragmentation scheme and machine learning force field to achieve ab initio accuracy on energy and force calculations for various proteins comprising over 10,000 atoms. Compared to quantum simulation approach, such as Density Functional Theory, it reduces computational time by several orders of magnitude. AI2BMD demonstrated its capability for efficiently exploring the conformational space of peptides and proteins, enabling precise thermodynamic property calculations that are well aligned with experiments. Raised by AI2BMD and other works, the coming age of AI driven biomolecular dynamics simulation could potentially complement wet-lab experiments, detect the dynamic processes of bioactivities, and enable biomedical research that is currently impossible to conduct.
