Among the four enzymes of the AsA-GSH pathway in chloroplasts, the chloroplastic APX (chAPX) which consists of thylakoid (tAPX) and stromal (sAPX) isoforms scavenges the H 2 O 2 generated during photosynthesis

This stress can worsen inflammation and damage healthy tissue

For biosynthesis of glutathione and homoglutathione share a common first reaction, i.e., the synthesis of -glutamylcysteine, but the chemical diversity results from altered specificity for the nucleophilic amino acid in the second reaction of the pathway

In contrast, our results demonstrated that the Q 67 residue is critical for GSH binding
