Protein attributes

Sequence length	527 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells.
Catalytic activity	2 H2O2 = O2 + 2 H2O.
Cofactor	Heme group By similarity. NADP By similarity.
Subunit structure	Homotetramer By similarity.
Subcellular location	Peroxisome By similarity.
Involvement in disease	Defects in CAT are the cause of acatalasia; also known as acatalasemia. This disease is characterized by absence of catalase activity.
Sequence similarities	Belongs to the catalase family.
