ELECTRODE, AND ENZYME SENSOR, FUEL CELL, ELECTRONIC DEVICE AND POLYOL DEGRADATION METHOD USING THE ELECTRODE

摘要

An electrode that can generate reduced coenzymes from a desired substrate in multiple stages is provided. An electrode includes a 2-hydroxycarboxylic acid synthase, a 2-oxo acid synthase, and a 2-oxo acid carboxylyase. The electrode includes a 2-oxo acid carboxylyase, which is a decarboxylase, in addition to a 2-hydroxycarboxylic acid synthase and a 2-oxo acid synthase, which are oxidoreductases; therefore, oxidation products having carboxyl groups, reactions of which do not proceed with oxidoreductases, can be decarboxylated and modified into substances with which oxidoreductases can act. Thus, oxidation reactions and decarboxylation reactions can repeatedly proceed with respect to desired substrates, and large quantities of reduced coenzymes can be generated thereby.
