Protein
Ferric reductase transmembrane component 5
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Metalloreductase responsible for reducing extracellular iron and copper prior to import. Catalyzes the reductive uptake of Fe(3+)-salts and Fe(3+) bound to catecholate or hydroxamate siderophores. 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).
Similarity
Belongs to the ferric reductase (FRE) family.
