1”c” or “b” denotes the type of cytochrome
2MQ menaquinone, UQ ubiquinone
3not further characterized
*”Ech-like complex” denotes for the presence of genes that encode proteins with similarity to some Ech subunits, but not a full complex
#”Fix-like complex” denotes for a complex present in quinone-free organisms; therefore, its function cannot be as described in quinone-containing organisms
