STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

azo3366Conserved hypothetical protein. Homology to rpa3088 of R. palustris of 65% (tremblnew|CAE28529). Pfam: Dinitrogenase iron-molybdenum cofactor. no signal peptide. no TMHs. (127 aa)    
Predicted Functional Partners:
azo3367
Putative NifZ Protein homolog, shares 45% similarity to SwissProt:P46040, NifZ protein entry. Has PF04319:IPR007415:NifZ domain;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 present. No TMH Present; High confidence in function and specificity.
 
     0.808
fer22
Probable ferredoxin 2fe-2s protein. Homology to fer2 of C. pasteruianum of 43% (sprot|FER2_CLOPA). Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. no signal peptide no TMHs; Family membership.
       0.775
modD
Putative molybdenum transport protein; Putative pyrophosphorylase modD (EC 2.4.2.-). InterPro: Quinolinate phosphoribosyl transferase; Specificity unclear; Belongs to the NadC/ModD family.
 
     0.721
fdxD
Ferredoxin V (FdV) (Ferredoxin plant-type). FERREDOXINS ARE IRON-SULFUR PROTEINS THAT TRANSFER ELECTRONS IN A WIDE VARIETY OF METABOLIC REACTIONS. THIS FERREDOXIN PROBABLY PARTICIPATES IN NITROGEN FIXATION. InterPro: Ferredoxin; High confidence in function and specificity.

cowN
Conserved hypothetical protein; Is required to sustain N(2)-dependent growth in the presence of low levels of carbon monoxide (CO). Probably acts by protecting the N(2) fixation ability of the nitrogenase complex, which is inactivated in the presence of CO.
  
     0.612
draT
Putative NAD(+)-dinitrogen-reductase ADP-D-ribosyltransferase (EC 2.4.2.37) (ADP-ribosyltransferase). Homology to draT of R. rubrum of 39% (sprot|DRAT_RHORU(SRS) Involved in the regulation of the nitrogen fixation activity by the reversible ADP-ribosylation of the dinitrogenase reductase component of the nitrogenase enzyme complex. The ADP-ribosyltransferase transfers the ADP-ribose group from NAD to dinitrogenase reductase. The ADP-ribose group is removed through the action of the ADP-ribosylglycohydrolase (DraG). Pfam: DRAT no signal peptide no TMHs; High confidence in function and s [...]
  
    0.516
nifQ
Putative NifQ protein. Homology to nifQ of A. vinelandii of 33% (sprot|NIFQ_AZOVI(SRS) NifQ is involved in early stages of the biosynthesis of the iron-molybdenum cofactor (FeMo-co), which is an integral part of the active site of dinitrogenase [2]. The conserved C-terminal cysteine residues may be involved in metal binding. Pfam: NifQ no signal peptide no TMHs; Family membership.
