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.
Developmental stage	Sporulation-specific.
Sequence similarities	Belongs to the catalase family.
Sequence caution	The sequence AAC49254.1 differs from that shown. Reason: Frameshift at positions 583 and 592.
