Photochemical Reduction of NADP^+ by Zinc Protoporphyrin Reconstituted Myoglobin as a Simple Model of Photosystem I
Photoinduced electron transfer between zinc protoporphyrin reconstituted myoglobin (Zn-Mb) and NADP<SUP>+</SUP> functions as a model of photosystem I by forming NADPH. The reduction efficiency of NADP<SUP>+</SUP> depended strongly on the solution pH, which was explained by the difference in the redox potential and/or the static interaction between Zn-Mb and a sacrificial donor triethanolamine (TEA).
