Nitro-fatty acids-mediated nitroalkylation modulates fine-tuning catalase antioxidant function during salinity stress in plants.

ABSTRACT: Nitro-fatty acids (NO₂-FAs) are novel molecules resulting from the interaction of unsaturated fatty acids and nitric oxide (NO) or NO-related molecules. In plants, it has recently been described that NO₂-FAs trigger a powerful antioxidant and defense response against stressful situations, the induction of the heat-shock response (HSR), and they exert their signaling function mainly through a reversible post-translational modification called nitroalkylation. Catalase (CAT) is a key antioxidant enzyme for the control of the hydrogen peroxide (H₂O₂) levels generated by environmental oxidative stress. The data presented in this study provide novel information on the role of NO₂-FAs in modulating the antioxidant activity of catalase 2 (CAT2
