CRYSTAL STRUCTURE OF HUMAN ERYTHROCYTE CATALASE

Template:ABSTRACT PUBMED 10666617

Disease

[CATA_HUMAN] Defects in CAT are the cause of acatalasemia (ACATLAS) [MIM:614097]. A metabolic disorder characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions.[1]

Function

[CATA_HUMAN] Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells.[2]

About this Structure

1qqw is a 4 chain structure with sequence from Homo sapiens. The September 2004 RCSB PDB Molecule of the Month feature on Catalase by David S. Goodsell is 10.2210/rcsb_pdb/mom_2004_9. Full crystallographic information is available from OCA.
