evolutionary trajectory of these oxidoreductases from a proton-reducing ancestral respiratory complex (ARC), overview. The diversification of ARC to membrane-bound hydrogenase (MBH), archaeal respiratory complex (MBX), FPO and eventually NADH quinone oxidoreductase (NUO) was driven by the larger energy yields associated with coupling ferredoxin oxidation to the reduction of oxidants with increasing electrochemical potential, including protons, S° and membrane soluble organic compounds such as phenazines and quinone derivatives. Phylogenetic tree. Homology between the subunits of FPOF and FPOC with those in MBX and MBH. Evolution of FPO, detailed overview. FPO is now present only in strictly anaerobic, acetate-utilizing and sulfate-reducing archaea

the enzyme is a methanophenzine-reducing subunit of a methanogenic respiratory complex (FPO). These complexes also pump ions and have at least 10 homologous subunits in common. FPO uses either ferredoxin or cofactor F420. The FPO complex is mainly found in acetate-utilizing, methane-producing anaerobic Archaea where it functions to reduce the membrane-associated cofactor methanophenazine using either ferredoxin or the cytoplasmic cofactor F420

FPO demonstrates the flexible nature of the ARC-related complexes with respect to electron input and energetics reflected by differences in redox carriers and number of ions translocated

FpoF can function as an ferredoxin:F420 oxidoreductase when reduced ferredoxin accumulates in the cytoplasm. As a soluble single subunit it is involved in the reoxidation of reduced ferredoxin in the cytoplasm, whereby reduced F420 is produced that is then reoxidized by the complete Fpo complex
