Cysteine zinc binding molecular dynamics

WebExtensive MD simulations of seven zinc enzyme systems with different coordination ligands and distinct chelation modes (four-, five-, and six-fold), including a binuclear zinc active site, yielded zinc coordination numbers and binding distances in good agreement with the corresponding crystal structures as well as ab initio QM/MM MD results. WebOct 11, 2024 · We show the molecular mechanism of this activation to be specific oxidation of a conserved cysteine that coordinates the zinc of its regulatory chemoreceptor zinc-binding (CZB) domain, forming a zinc-cysteine redox switch 685-fold more sensitive to oxidation by HOCl over H 2 O 2.
