Hydrogenases catalyze the reversible oxidation of molecular hydrogen (H(2)), but little is known about the diffusion of H(2) toward the active site. Here we analyze pathways for H(2) permeation using molecular dynamics (MD) simulations in explicit solvent. Various MD simulation replicates were done, to improve the sampling of the system states. H(2) easily permeates hydrogenase in every simulation and it moves preferentially in channels. All H(2) molecules that reach the active site made their a ...[more]
