Interprotein Electron Transfer between FeS‐Protein Nanowires and Oxygen‐Tolerant NiFe Hydrogenase

Self‐assembled redox protein nanowires have been exploited as efficient electron shuttles for an oxygen‐tolerant hydrogenase. An intra/inter‐protein electron transfer chain has been achieved between the iron‐sulfur centers of rubredoxin and the FeS cluster of [NiFe] hydrogenases. [NiFe] Hydrogenases entrapped in the intricated matrix of metalloprotein nanowires achieve a stable, mediated bioelectrocatalytic oxidation of H2 at low‐overpotential. Selbstorganisierte Redoxprotein‐Nanodrähte bewirken den effizienten Elektronentransport in einer sauerstoffverträglichen Hydrogenase. In einem Geflecht aus Metalloprotein‐Nanodrähten eingebettete [NiFe]‐Hydrogenasen vermitteln stabil die bioelektrokatalytische H2‐Oxidation bei geringem Überpotential.
