Ascorbate peroxidase (APX) is one of the major antioxidant enzymes involved in the detoxification of hydrogen peroxide. APX is found in chloroplast, cytosol and microsomes. The structural model for the APX izozymes has not been solved. In the present study, we describe the structural model for the chloroplast APX of Ipomea nil (morning glory) using homology model, which provides an insight for better understanding of APX molecular function in providing oxidative stress tolerance in plants.
