Keyword - Peroxisome (KW-0576)


Protein found in or associated with the peroxisome, a small eukaryotic organelle limited by a single membrane, specialized for carrying out oxidative reactions. Contains mainly peroxidases, several other oxidases and catalase. The catalase regulates the contents of the produced toxic hydrogen peroxide thus protecting the cell. Beta-oxidation of fatty acids is another major function of peroxisomes. In plants and fungi this degradation occurs only in this cellular compartment.
