General annotation (Comments)

Function	Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide.
Catalytic activity	2 H2O2 = O2 + 2 H2O.
Cofactor	Heme group.
Subunit structure	Homotetramer By similarity.
Subcellular location	Peroxisome By similarity.
Tissue specificity	In stems, leaves, roots and developing fruits.
Induction	In roots, by aluminum and salt. Expressed with a circadian rhythm reaching a maximum at late in the dark period or early in the light period.
Sequence similarities	Belongs to the catalase family.
