CAT — Capsicum annuum

Summary

The pepper (Capsicum annuum) gene T459_31094 (symbol CAT, also known as CaCat3, CaCAT2, CAT2, CAT-1, CaCAT, CaCAT-1) on chromosome 12 encodes a catalase enzyme with catalase activity and heme binding, belonging to the catalase superfamily. The encoded protein localizes to the peroxisomal lumen, cytosol, and cytoplasm. CAT is associated with biological processes including heat dissipation, nitrogen fixation, the ascorbate-glutathione cycle, carotenoid metabolism, cellular respiration, fermentation, root system development, and hormone metabolism. The gene is linked to traits such as drought tolerance, chilling stress response, salt stress tolerance, fruit ripening, pungency, photosynthetic rate, chlorophyll content, plant height, root length, germination rate, and protein, amino acid, proline, and carotenoid content. It is also associated with antioxidant activity and oxidative stress response.
