CC   -!- FUNCTION: Occurs in almost all aerobically respiring organisms and
CC       serves to protect cells from the toxic effects of hydrogen
CC       peroxide.
CC   -!- CATALYTIC ACTIVITY: 2 H(2)O(2) = O(2) + 2 H(2)O.
CC   -!- COFACTOR: Heme group.
CC   -!- SUBUNIT: Homotetramer.
CC   -!- SUBCELLULAR LOCATION: Peroxisome.
CC   -!- MISCELLANEOUS: There are at least five isozymes of catalase in
CC       cotton.
CC   -!- SIMILARITY: Belongs to the catalase family.
