A molecular pendulum for efficient hydrogen production
Researchers at Ruhr University Bochum have shown how zinc inhibits [FeFe]-hydrogenases, enzymes that produce hydrogen, by binding two surface histidines near a known proton transport pathway. One histidine acts as a molecular pendulum, receiving a proton at the enzyme surface and delivering it inward. Replacing it slowed hydrogen production; replacing the other left the enzyme active but zinc insensitive.
