About this paper
Timothy T. Duignan
Simulations of Carbonic Anhydrase II using the Orb universal neural network potential revealed an alternative reaction pathway for bicarbonate formation, where CO2 reacts with an adjacent water molecule while the zinc-bound hydroxide acts as a base. The study also elucidated detailed proton transfer pathways and CO2 binding dynamics within the enzyme's active site.
Key insights
- Universal neural network potentials can accurately and efficiently simulate reactive events, including complex metal coordination, in large biological systems.
- Enzymatic catalysis, exemplified by CA II, may involve multiple, potentially redundant, proton transfer pathways to ensure efficiency.
- Water molecules can actively participate as direct reactants in enzymatic mechanisms, not solely as passive solvents or proton relays.
