University of Leiden find micro-movements in laccase enzyme could help biofuel cells

In the Netherlands, University of Leiden researchers have found minute movements in the laccase enzyme, a very efficient catalyst, which makes it interesting for use in biofuel cells.

The laccase enzyme is able to efficiently create water from oxygen without creating hydrogen peroxide, an unstable compound that would damage biofuel cells. Because proteins tend to be unstable, scientists have tried to recreate laccase’s properties in more durable inorganic compounds.

While these new inorganic compounds are sturdier than the original proteins, they are not as efficient. A new discovery by Leiden chemists opens up new possibilities to improve the inorganic replicas.
