Synthetic chemistry:  Making a natural fuel cell

Marcetta York Darensbourg1

The synthetic assembly of the active centre of hydrogen-producing enzymes adds to our understanding of their structure and function — and could produce new and useful materials that mimic these enzymes.

A host of microbes metabolize hydrogen with high efficiency by using enzymes known as hydrogenases1. These enzymes are exquisite miniature hydrogen fuel cells, and are based on a combination of sulphur and iron atoms, and sometimes a single nickel atom2.
