Bonds from bands

[FeFe]-hydrogenases are enzymes that catalyse the interconversion of protons, electrons and dihydrogen. Hydrogenase mechanisms have inspired many strategies to produce H2 as a ‘green fuel’. A landmark study from 15 years ago established much of what we know about these intricate mechanisms.
