These functions might be dependent on each isozyme/isoform in each plant tissue.FUNCTION:May contribute to protection against cold-induced oxidative stress.CATALYTIC ACTIVITY:Donor H(2)O(2) = oxidized donor 2 H(2)O.COFACTOR:Binds 2 calcium ions per subunit.COFACTOR:Binds 1 heme B (iron-protoporphyrin IX) group per subunit.TISSUE SPECIFICITY:Highly expressed in suspension cultured cells.Weak expression also found in the stems of intact plants. No expression in leaf, tuberous root and non-tuberous root.DEVELOPMENTAL STAGE:Very low expression level 0.5 days after subculture (DAS).INDUCTION:By wounding and cold stress. Induced by acclimation and repressed by chilling.SIMILARITY:Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily."
