frp2

Ferric/cupric reductase transmembrane component 2

564 amino acids

Metalloreductase responsible for reducing extracellular iron and copper prior to import (By similarity). Catalyzes the reductive uptake of Fe(3+)-salts and Fe(3+) bound to catecholate or hydroxamate siderophores (By similarity). Fe(3+) is reduced to Fe(2+), which then dissociates from the siderophore and can be imported by the high-affinity Fe(2+) transport complex in the plasma membrane (By similarity). Also participates in Cu(2+) reduction and Cu(+) uptake (By similarity).

Belongs to the ferric reductase (FRE) family.
