Medical Definition of Peroxidase

1. A haem enzyme that catalyses reduction of hydrogen peroxide by a substrate that loses two hydrogen atoms. Within cells, may be localised in peroxisomes. Coloured reaction products allow detection of the enzyme with high sensitivity, so peroxidase coupled antibodies are widely used in microscopy and ELISA. Lactoperoxidase is used in the catalytic surface labelling of cells by radioactive iodine. This entry appears with permission from the Dictionary of Cell and Molecular Biology (11 Mar 2008)
