Protein
Formate dehydrogenase, nitrate-inducible, major subunit
Gene
fdnG, b1474, JW1470
Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Formate dehydrogenase allows E.coli to use formate as major electron donor during anaerobic respiration, when nitrate is used as electron acceptor. The alpha subunit FdnG contains the formate oxidation site. Electrons are transferred from formate to menaquinone in the gamma subunit (FdnI), through the 4Fe-4S clusters in the beta subunit (FdnH). Formate dehydrogenase-N is part of a system that generates proton motive force, together with the dissimilatory nitrate reductase (Nar).1 Publication

Catalytic activityi

Formate + a quinone = CO2 + a quinol.1 Publication
