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.
