【 摘 要 】

The interaction of ferredoxin with thylakoids is shown to occur at two distinct sites: at the reducing end of photosystem I, and at the site where ferredoxin-NADP reductase (FNR) is located on the membrane. The evidence is based on the lack of inhibition of ferredoxin photoreduction by the extraction of FNR or its inactivation by an antibody, and on the difference between K _m values for ferredoxin in reactions requiring FNR as compared to those only requiring ferredoxin.
