Abstract

Microperoxidase-11 (MP-11) assembled onto an Au electrode catalyzes the electroreduction of a series of hemoproteins: cytochrome c (Cyt. c) myoglobin (Mb) and hemoglobin (Hb). The electrical contact between MP-11 and the hemoproteins originates from intermolecular complexes between MP-11 and the different hemoproteins. The MP-11-functionalized electrode catalyzes the reduction of cytochrome-dependent nitrate reductase and mediates the bioelectrocatalyzed reduction of nitrate to nitrite. The systems provide assemblies mimicking inter-protein electron transfer in hemoproteins.
