Thylakoid Rhodanese-like Protein–Ferredoxin:NADP<sup>+</sup> Oxidoreductase Interaction Is Integrated into Plant Redox Homeostasis System
Published 2023-10-01“…In this work, we aimed to further test our hypothesis that the FNR–TROL pair could be the source element that triggers various downstream networks of chloroplast ROS scavenging. Tandem affinity purification followed by the MS analysis confirmed the TROL–FNR interaction and revealed possible interaction of TROL with the thylakoid form of the enzyme ascorbate peroxidase (tAPX), which catalyzes the H<sub>2</sub>O<sub>2</sub>-dependent oxidation of ascorbate and is, therefore, the crucial component of the redox homeostasis system in plants. …”
