✦ Synopsis
The feasibility of using an electrode as an electron source to promote the reduction of triphosphopyridine nucleotide (TPN)** through the reaction sequence shown in Fig. 1 was demonstrated recently by a group at TRW Systems 1. The objective of the TRW group was to substitute the photosynthetic route with an electrochemical one for the release of oxygen and the assimilation of carbon dioxide. In their work, methyl viologen was used as the electron carrier or mediator and in the presence of spinach ferredoxin-TPN-reductase (FTR), promoted electron transfer to reduce TPN to TPNH.
