Hypothetical protein; 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; In the N-terminal section; belongs to the complex I 30 kDa subunit family.

Hypothetical protein; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.

Hypothetical protein; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins.

Hypothetical protein; KEGG: ecp:ECP_1403 0. probable pyruvate-flavodoxin oxidoreductase K03737; COG: COG1013 Pyruvate:ferredoxin oxidoreductase and related 2-oxoacid:ferredoxin oxidoreductases, beta subunit.

Hypothetical protein; A scaffold on which IscS assembles Fe-S clusters. It is likely that Fe-S cluster coordination is flexible as the role of this complex is to build and then hand off Fe-S clusters.

Hypothetical protein; KEGG: stm:STM3219 0. fadH; 2,4-dieonyl-CoA reductase K00219; COG: COG0446 Uncharacterized NAD(FAD)-dependent dehydrogenases; Psort location: Cytoplasmic, score:8.96.

Hypothetical protein; KEGG: eci:UTI89_C2794 1.1e-226 aegA, yffG; putative oxidoreductase Fe-S subunit K00264; COG: COG0493 NADPH-dependent glutamate synthase beta chain and related oxidoreductases; Psort location: Cytoplasmic, score:9.97.

Hypothetical protein; Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component; Belongs to the NADPH-dependent sulphite reductase flavoprotein subunit CysJ family. In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.

Hypothetical protein; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. Belongs to the complex I 51 kDa subunit family.
