General Information | Comment | Organism |
---|---|---|
additional information | introduction of specific disulfide bonds between ferredoxin and Fd-NADP+ reductase by engineering cysteines into the two proteins results in 13 different Fd-FNR cross-linked complexes displaying a broad range of activity to catalyze the NADPH-dependent cytochrome c reduction | Zea mays |
physiological function | ferredoxin and Fd-NADP+ reductase are redox partners responsible for the conversion between NADP+ and NADPH in the plastids of photosynthetic organisms | Zea mays |
