Probable formate dehydrogenase (NADP+), beta subunit Homology to fdh1B of M. extorpuens of 55% (trembl|Q8KTI8) Pfam: Respiratory-chain NADH dehydrogenase 24 kD subunit; Respiratory-chain NADH dehydrogenase 51 kD subunit. no signal peptide no TMHs; High confidence in function and specificity.

NifU-related 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.

Probable nitrogen fixation protein NifU; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.

Putative regulatory Protein yfhF, 72% identity (82% similarity) to TrEMBL;P36539 of E.coli. Has PF01521, HesB-like domain;(IPR000361, HesB_yadR_yfhF); This family includes HesB which 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 P46847 and NP31774 also contains NifU-like domains NifU 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; High confidence [...]

Probable putidaredoxin reductase (EC 1.18.1.-). Homology to camA of P. putida of 48% (sprot|CAMA_PSEPU). The oxidation of camphor by cytochrome p450-cam requires the participation of a flavoprotein, putidaredoxin reductase, and an iron-sulfur protein, putidaredoxin, to mediate the transfer of electrons from nadh to p450 for oxygen activation. Interpro: FAD-dependent pyridine nucleotide-disulphide oxidoreductase (IRP001327), NAD binding site (IPR000205) Pfam: Pyridine nucleotide-disulphide oxidoreductase no signal peptide no TMHs; Family membership.

Conserved hypothetical protein. Homology to CV1087 of C.violaceum of 69% (trembl:Q7NZ35). Has PF04384; Protein of unknown function (DUF528);IPR007479: Small bacterial protein of unknown function. No signal peptide or TMH present.

Putative co-chaperone HscB; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family.

Cysteine desulfurase; 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.

Probable cysteine desulfurase (NifS protein homolog). Homology to iscS of M. thermophila of 40% (sprot|ISCS_METTE) Catalyzes the removal of elemental sulfur from cysteine to produce alanine (By similarity). InterPro: Aminotransferase class-V (IPR000192) Pfam: aminotransferase class-V no signal peptide no TMHs ahpD: alkylhydroperoxidase AhpD; Family membership.
