Cover Story: The electrochemical gradient requires constant cation transport to the outside of a (bacterial) cell against a concentration gradient. Their influx, in turn, drives ATP synthesis and is vital for every living cell. Respiratory proteins generate the gradient through energy released from the catalyzed redox reactions. One prominent example is the proton-pumping complex I of the mitochondrial respiratory chain. The phylogenetically related enterobacterial formate hydrogenlyase catalyzes formate oxidation with concomitant hydrogen (H2) production. Despite the similarity to complex I, we found that H2 production depended upon proton influx and cation export. However, the freely diffusible H2 is converted to protons by outside hydrogenases and thus contributes there to the proton gradient through hydrogen cycling. View this paper.

Fermentative hydrogen production by enterobacteria derives from the activity of the formate hydrogenlyase (FHL) complex, which couples formate oxidation to H2 production. The molybdenum-containing formate dehydrogenase and type-4 [NiFe]-hydrogenase t...
