Abstract The active sites of metalloenzymes involved in small molecules activation often contain pendant bases that act as proton relay promoting proton‐coupled electron‐transfer processes. Here we focus on hydrogenases and the reactions they catalyze, i. e. hydrogen evolution oxidation reactions. After a short description these enzymes, review some various biomimetic bioinspired molecular systems relays. We then provide formal electrochemical framework required to decipher key role such enhance catalysis single direction discuss few for H 2 which quantitative kinetic data are available. finally highlight parameters reach bidirectional (both catalyzed) transition reversible catalyzed narrow potential range) well illustrate features from literature.
