Glutathione (GSH) peroxidase (GPx) activity assays of PgpD and CgpD. A) Histidine-tagged CgpD and PgpD proteins were purified. B) Glutathione was added and the peroxidase activity is defined as the amount of hydrogen peroxide (mg) broken down in one minute (min) by one mg of purified enzymes (mg H2O2/min/mg) under the assay conditions described.
