Web5. nov 2024 · Redox regulation, based on disulfide–dithiol exchange, constitutes an essential regulatory mechanism that allows the rapid adaptation of chloroplast metabolism to changes in light intensity ( Buchanan, 2016 ). WebIn plant chloroplasts redox regulation is essential for the rapid adaptation of metabolism to ever changing light availability. Chloroplasts harbor a complex set of Trxs and Trx-like proteins, which rely on photo-reduced Fdx via the participation of FTR, thus linking redox regulation of enzyme activity to light.
