Abstract:Nicotinamide adenine dinucleotide-dependent formate dehydrogenase
from Candida boidinii was immobilized
in a 1,2-dimyristoyl-sn-glycero-3-phosphocholine/cholesterol
floating lipid bilayer on the gold surface as a biocatalyst for electrochemical
CO2 reduction. We report that, in contrast to common belief,
the enzyme can catalyze the electrochemical reduction of CO2 to formate without the cofactor protonated nicotinamide adenine
dinucleotide. The electrochemical data indicate that the enzyme-catalyzed
reduction … Show more
