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

cowNConserved 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. (126 aa)    
Predicted Functional Partners:
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 [...]

draG1
Probable ADP-ribosyl-[dinitrogen reductase] hydrolase. Homology to draG of R. rubrum of 44% (sprot|DRAG_RHORU) 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 (DraT) 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: ADP-ribosylglycohydrolase no signal peptide no TMHs.

Conserved hypothetical protein. Homology to rpa3088 of R. palustris of 65% (tremblnew|CAE28529). Pfam: Dinitrogenase iron-molybdenum cofactor. no signal peptide. no TMHs.
  
     0.612
fdxB
Probable ferredoxin. Homology to fdxB of R. capsulatus of 45% (sprot|FER3_RHOCA) Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. InterPro: 4Fe-4S ferredoxin iron-sulfur binding domain (IPR001450) Pfam: 4Fe-4S binding domain no signal peptide no TMHs; Family membership.

pflA
Conserved hypothetical pyruvat formate-lyase activiating enzyme. Homology to pflA of M. tuberculosis of 64% (trembl|P95188). no domains predicted no signal peptide no TMHs; Family membership.
       0.554
nifY1
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.

azo1679
Hypothetical protein, 38% identity to SwissProt;O26945 Has PF01871;AMMECR1;(IPR002733, DUF 51)This family consists of several AMMECR1 as well as several uncharacterised proteins. The contiguous gene deletion syndrome AMME is characterised by Alport syndrome, midface hypoplasia, mental retardation and elliptocytosis and is caused by a deletion in Xq22.3,comprising several genes including COL4A5, FACL4 and AMMECR1. This family contains sequences from several eukaryotic species as well as archaebacteria and it has been suggested that the AMMECR1 protein may have a basic cellular function, [...]

Hypothetical UPF0103 protein ST2062. This gene is conserved in several species ranging from Caenorhabditis elegans and yeast to plants and micro-organisms although no function has yet been ascribed to the other proteins in this family. TREMBL:Q843N3: 38% identity,52% similarity InterPro:IPR002733; DUF51. IPR002737; DUF52. Pfam: PF01871; AMMECR1; 1.

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.
