Figure 7 The correlation between GSH and phycocyanin; GSH and SOD enzyme
GSH, together with SOD, acts as the core antioxidant factor of the redox system, scavenging free radicals and preventing damage from peroxidation reactions. Enhancement of GSH regulation by biological γ-glutamylcysteine synthetase promotes GSH regeneration. γ-glutamylcysteine synthetase (γ- ECS) and glutathione synthetase (GS), play key roles in the synthesis of GSH in Microcystis aeruginosa. γ- ECS can control the rate of GSH synthesis, and in turn GSH can also provide feedback inhibition of γ- ECS, as Fig.8.
