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.

Conserved hypothetical protein. Homology to an orf of Pseudomonas stutzeri of 52% (tremble:Q9EVM9). No domains predicted. No TMHs. No signal peptide.

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.

Probale Hypothetical protein. Very Weak homology spanning the entire length of protein in the data base. No Significant domains,Features,TMH's or Signal Peptide present; Function unclear.

Conserved hypothetical protein Shows similarity to hypothetical 7.7 kDa protein in fixX 3'region (ORF1) of Azorhizobium caulinodans. TIGR00162: conserved hypothetical protein.

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

NifY-like protein. Homology to Daro03003760 of Dechloromonas aromatica of 65% (gi|46140358|ref|ZP_00203574.1|(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; Family membership.

Nitrogen fixation regulatory protein (EC 2.7.3.-). Required for the inhibition of nifA activity in response to oxygen and low level of fixed nitrogen. Similar to SWISSPROT: sprot|NIFL_AZOVI (41% Azotobacter vinelandii,nitrogen fixation regulatory protein (EC 2.7.3.-), NifL) InterPro: IPR003661 His_kinA_N.
