ferredoxinthioredoxinsystemet
The ferredoxin-thioredoxin system is a crucial regulatory pathway in photosynthesis found in many organisms, including plants, algae, and cyanobacteria. It plays a vital role in managing the redox state of the cell, particularly in response to light availability. The system consists of three main components: ferredoxin, thioredoxin, and a specific reductase enzyme.
Ferredoxin is a small iron-sulfur protein that receives electrons directly from the photosynthetic electron transport chain.
The reduced form of thioredoxin is a potent reducing agent that can modulate the activity of various
