Formate dehydrogenase-N

Formate dehydrogenase-N (EC 1.1.5.6, Fdh-N, FdnGHI, nitrate-inducible formate dehydrogenase, formate dehydrogenase N, FDH-N, nitrate inducible Fdn, nitrate inducible formate dehydrogenase) is an enzyme with systematic name formate:quinone oxidoreductase.^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

formate + quinone

\rightleftharpoons

CO₂ + quinol

This enzyme contains molybdopterin-guanine dinucleotides, five [4Fe-4S] clusters and two heme b groups.
