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

nifQPutative 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. (191 aa)    
Predicted Functional Partners:
csdB
Cysteine desulphurases required for the mobilization of sulphur from cysteine. They are present in all organisms, where they are involved in iron-sulphur (Fe-S) cluster biosynthesis. Similar to sprot|CSD1_MYCLE (54%), to trembl|Q82WT8 (55%) and to tremblnew|BAB21542 (34%). Pfam (PF00266): Aminotransferase class-V Pfam (PF01041): DegT/DnrJ/EryC1/StrS aminotransferase family; Function unclear.

nifS
Cysteine desulphurase; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine.
 
 0.973
iscS1
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.
  
 0.967
iscS2
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.
  
 0.967
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.
 
 0.963
cyaY
Putative CyaY protein; Involved in iron-sulfur (Fe-S) cluster assembly. May act as a regulator of Fe-S biogenesis.
    
 0.958
hscB
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.
  
 
 0.956
fdxC
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.
 
 0.911
nifB
Nitrogen fixation protein; FeMo cofactor biosynthesis protein nifB. PROBABLY INVOLVED IN THE SYNTHESIS OF THE FE-MO COFACTOR; High confidence in function and specificity.
 
  
 0.897
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.
