HORSERADISH PEROXIDASE C1A
|
Horseadish (Armoracia rusticana) is a plant that belongs to the Brassicaceae family. The roots of this plant are rich in peroxidases, being the HRP C isozymes the most common ones. [1] However, most of the HRP research has focused on one isozyme: [2].
Structural highlights
HRP C1A is composed by 308 residues and has a predominantly α-helical , with the exception of one short β-sheet region. The molecule is separated into a distal and a proximal region, each one with a . In the center of the molecule there is a , which is linked to the molecule by a coordinate bond of the heme iron with a conserved [1]. Other residues play essencial roles in the the molecule, as the and , which are related to the formation and stabilization of , that is the active form of the enzyme.
