3.D.6.1.1 | NADH:ferredoxin oxidoreductase | Bacteria |
Proteobacteria | RnfABCDEG of Rhodobacter capsulatus |
|
3.D.6.1.2 | The Rnf-type NADH dehydrogenase, RnfABCDEG (Imkamp et al., 2007). Note: RnfD may be truncated as almost all homologues have 300-330aas with 6-7 TMSs. This system has been shown to pump Na+ out of the cell when reducing NAD+ with reduced ferredoxin, and dependent on the smf for reduction of ferredoxin with NADH2 (Hess et al. 2013). | Bacteria |
Firmicutes | RnfABCDEG of Acetobacterium woodii: RnfA (195 aas) (C4N8U4) RnfB (333 aas) (C4N8U5) RnfC (443aas) (C4N8U0) RnfD (132aas) (C4N8U1) RnfE (196 aas) (C4N8U3) RnfG (207 aas) (C4N8U2) |
|
3.D.6.1.3 | The Rnf-type NADH dehydrogenase, RnfABCDEG/MA0658 (Welte and Deppenmeier 2013). RnfB and RnfC are on the cytoplasmic side of the membrane. Both have 4Fe4S centers (5 and 2, repectively), and RnfB oxidizes reduced ferredoxin (Suharti et al. 2014). The integral membrane proteins are RnfA, D and E, while RnfG and MA0658 are on the outside. RnfE reduces oxidized Mph (Welte and Deppenmeier 2013). | Archaea |
Euryarchaeota | RnfABCDEG/MA0658 complex of Methanosarcina acetivorans RnfA, 199 aas RnfB, 264 aas RnfC, 447 aas RnfD, 288 aas RnfE, 213 aas RnfG, 188 aas MA0658, 500 aas |
|
3.D.6.1.4 | Rnf-type NADH dehydrogenase, RsxA, RsxD, RsxE, RsxG, RsxB, RsxC of 6, 10, 5, 1, 1 and 1 TMSs, respectively. | Bacteria |
Proteobacteria | Rnf-like system, RsxA, B, C, D, E, G of E. coli |
