Background: Myeloperoxidase/MPO

Myeloperoxidase (MPO) is a hemeprotein that belongs to the XPO subfamily of the heme peroxidase superfamily. MPO is synthesized as a preproprotein that undergoes proteolytic processing to generate a disulfide-linked heterodimer of the N-terminal beta -subunit (12 kDa) and C-terminal alpha subunit (60 kDa). Active MPO is a tetramer of two beta -subunits and two alpha -subunits that are also disulfide-linked through the two alpha -subunits. MPO is stored in granules and is an abundant protein in neutrophils and monocytes. MPO is released upon activation to catalyze the formation of powerful oxidants such as hypochlorous acid, which kills microbes. Unprocessed pro-MPO can also be released. Human and mouse MPO share 87% amino acid sequence identity.
