Nitrogen fixation protein [nifT],51% identity(72% Similarity) to SwissProt;P09427, TrEMBL;Q93JU8,57% identity. Has PF06988:NifT/FixU protein(IPR009727);This family consists of several NifT and FixU bacterial proteins. The function of NifT is unknown although it is thought that the protein may be involved in biosynthesis of the FeMo cofactor of nitrogenase although perturbation of nifT expression in K. pneumoniae has only a limited effect on nitrogen fixation. No Signal peptide or TMH present; High confidence in function and specificity.

Ferredoxin IV (FdIV) (Ferredoxin plant-type). Homology to fdxC of R. capsulatus of 62% (FER4_RHOCA). FERREDOXINS ARE IRON-SULFUR PROTEINS THAT TRANSFER ELECTRONS IN A WIDE VARIETY OF METABOLIC REACTIONS. THIS FERREDOXIN PROBABLY PARTICIPATES IN NITROGEN FIXATION. Pfam: 2Fe-2S iron-sulfur clauster binding domain no signal peptide no TMHs; High confidence in function and specificity.

ORF1; Conserved hypothetical protein. Homology to orf1 of Azoarcus sp. BH72 of 100% (gi|11493650|gb|AAG35591.1|(NBCI ENTREZ)). No domains predicted. No TMHs. No signal peptide.

Conserved hypothetical protein(Has probable Nif-associated protein function)41% identity(62% similarity) to TrEMBL;Q9KJL5. Has PF03270(IPR004952):Protein of unknown function, DUF269;Members of this family may be involved in nitrogen fixation, since they are found within nitrogen fixation operons. NO Signal Peptide or TMH present; Family membership.

Nitrogen Fixation protein[nifZ], 51% identity (67% similarity) SwissProt;P14889,66% similarity to SwissProt;P23124. Has PF04319:NifZ domain;(IPR007415)This short protein is found in the nif (nitrogen fixation) operon. Its function is unknown but is probably involved in nitrogen fixation or regulating some component of this process. This 75 residue region is presumed to be a domain. It is found in isolation in some members and in the amino terminal half of the longer NifZ proteins. No Signal Peptide Or TMH reported Present; High confidence in function and specificity.

NifY protein. Homology to nifY of Azoarcus sp. BH72 of 99% (gi|11493644|gb|AF200742.1|AF200742(NBCI ENTREZ)). Pfam: Dinitrogenase iron-molybdenum cofactor. This family contains several NIF (B, Y and X) proteins which are involved in the synthesis of an iron-molybdenum cofactors (FeMo-co) in the dinitrogenase enzyme which catalyses the reduction of dinitrogen to ammonium. No signal peptide predicted. No TMHs; Function unclear.

Conserved hypothetical protein. Homology to Daro03001685 of Dechloromonas aromatica of 46% (gi|41725028|ref|ZP_00151838.1|(NBCI ENTREZ)). No domains predicted. No TMHs. No signal peptide.

Conserved hypothetical protein. Homology to orf8 of Azotobacter vinelandii of 36% (tremble:Q44542). No domains predicted. No Signal peptide or TMH present.

Conserved hypothetical protein. Has PF05484:LRV protein FeS4 cluster(IPR008665);This Iron sulphur cluster is found at the N-terminus of some proteins containing LRV repeats. Has 6,(IPR004830) PF01816:Leucine rich repeat variant;The function of this repeat is unknown. It has an unusual structure of two helices. One is an alpha helix,the other is the much rarer 3-10 helix; Function unclear.
