| CBL57084.1 | nifU1 | PFREUD_15860 | PFREUD_14930 | HesB. may be involved in nitrogen fixation; the hesB gene is expressed only under nitrogen fixation conditions. Other members of this family include various hypothetical proteins of which some also contain NifU-like domains pfam01106 which is also involved in nitrogen fixation. In the gram-negative soil bacterium Rhizobium etli, the hesB-like gene iscN is required for nitrogen fixation; Belongs to the HesB/IscA family. | Nitrogen-fixing NifU-like; The nif genes are responsible for nitrogen fixation. However this domain is found in bacteria that do not fix nitrogen, so it may have a broader significance in the cell than nitrogen fixation. | 0.825 |

| feoA | feoB | PFREUD_19660 | PFREUD_19650 | Ferrous iron transport protein A; This family includes FeoA a small protein, probably involved in Fe2+ transport. This presumed short domain is also found at the C-terminus of a variety of metal dependent transcriptional regulators. This suggests that this domain may be metal-binding. In most cases this is likely to be either iron or manganese. | Fe2+ transport system protein B. Molecular function: GTP binding, iron ion binding. Cellular component: integral to membrane. | 0.962 |

| ilvD | nuoI | PFREUD_18990 | PFREUD_05240 | Dihydroxy-acid dehydratase; Belongs to the IlvD/Edd family. | NADH-quinone oxidoreductase subunit I (NADH dehydrogenase I subunit I) (NDH-1 subunit I); NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient. | 0.626 |
