Relationship Between the Primary Structure of Ferredoxin and Thioredoxin and Their Reactivity
Higher plants, algae and cyanobacteria possess a regulatory sytem. the ferredoxin- thioredoxin system, in which a light signal is converted into an electronic signal, which in turn generates the appearance of strongly reducing thiol groups. This system is able to photoregulate chloroplastic enzymes through thiol/ disulfide interchange reactions. In this regulatory chain, the ferredoxin- thioredoxin reductase is the only component restricted to photosynthetic cells.
