Abstract

During catalysis by hydrogenases, entities no larger than H2 or H+ reach and leave a deeply buried active site, by as yet unidentified pathways. Novel experiments, conducted mainly with the membrane-bound [NiFe]-hydrogenase from Ralstonia eutropha, explore why small excess gas pressures (H2 or He) attenuate the rate of H2 oxidation.
