Abstract

Super-reduced and super-active: A new redox state in the active site of algal [FeFe] hydrogenases has been identified and characterized by EPR and FTIR spectroscopy. Electrochemical and in-vitro essays show that this species is highly active in hydrogen production and suggest that it is a key intermediate in the catalytic cycle of all [FeFe] hydrogenases.
