Some proteins in the body have the ability to transfer electrons to or accept them from other molecules. How readily one of these proteins takes on new electrons is indicated by its so-called redox potential, measured in volts. Now researchers have modified a protein to tune its electron-transfer ability across a 2-V range—the first time variants of a single protein have been designed to adopt such a wide range of redox potentials.

The achievement shows . . .
