Ascorbic Acid 81-90 peroxidase N1 Nicotiana tabacum 58-68 16817898-1 2006 Ascorbate peroxidase isoforms localized in the stroma and thylakoid of higher plant chloroplasts are rapidly inactivated by hydrogen peroxide if the second substrate, ascorbate, is depleted. Ascorbic Acid 167-176 peroxidase N1 Nicotiana tabacum 10-20 14593802-4 2003 In the photoautotrophically grown plantlets and those photomixotrophically grown with 3% sucrose, the increase of growth irradiance from 80 to 380 mumol m-2 s-1 stimulated the activities of ascorbate-glutathione cycle enzymes with the exception of ascorbate peroxidase. Ascorbic Acid 190-199 peroxidase N1 Nicotiana tabacum 258-268 18512255-5 2008 Although antioxidant protection usually decreased in whole leaves of senescing control plants, ascorbate peroxidase (APX) and dehydroascorbate reductase (DHAR) activity, which maintained the high redox state of ascorbate, increased in chloroplasts of old control leaves. Ascorbic Acid 95-104 peroxidase N1 Nicotiana tabacum 105-115
