Gene: Sopen02g028410

General Information

Description Encodes a microsomal ascorbate peroxidase APX3. Ascorbate peroxidases are enzymes that scavenge hydrogen peroxide in plant cells. Eight types of APX have been described for Arabidopsis: three cytosolic (APX1, APX2, APX6), two chloroplastic types (stromal sAPX, thylakoid tAPX), and three microsomal (APX3, APX4, APX5) isoforms. The APX3 protein interacts with AKR2 (ankyrin-containing protein that interacts with AFT1) and AFT1, a 14-3-3 protein. | ascorbate peroxidase 3 (APX3) | FUNCTIONS IN: L-ascorbate peroxidase activity | INVOLVED IN: response to oxidative stress | LOCATED IN: in 7 components | EXPRESSED IN: 26 plant structures | EXPRESSED DURING: 16 growth stages | CONTAINS InterPro DOMAIN/s: Haem peroxidase , Plant ascorbate peroxidase , Peroxidases heam-ligand binding site , Haem peroxidase, plant/fungal/bacterial , Peroxidase, active site | BEST Arabidopsis thaliana protein match is: ascorbate peroxidase 5
