Enzyme catalysis: Three dehydrogenases have been engineered to self-assemble into a hydrogel that supports a synthetic metabolic network. The new catalytic biomaterial was used as an anode modification in two enzymatic biobatteries capable of the complete oxidation of methanol to CO2 (see picture).
