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

hesBHesB/yadR/yfhF family protein, 45% identity to TrEMBL;Q9KJL2,Q6HRJ0. SwissProt;P37026(41% identity) Has PF01521, HesB-like domain;IPR000361, HesB_yadR_yfhF;This family includes HesB which may be involved in nitrogen fixation; the hesB gene is expressed only under nitrogen fixation conditions. Other members of this family include various hypothetical proteins of which P46847 and NP31774 also contains NifU-like domains NifU which is also involved in nitrogen fixation. In the gram-negative soil bacterium Rhizobium etli, the hesB-like gene iscN is required for nitrogen fixation; High confi [...] (107 aa)    
Predicted Functional Partners:
nifU
Probable nitrogen fixation protein NifU; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
  
 
 0.985
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.
  
 
 0.797
nifS
Cysteine desulphurase; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine.

azo0983
Conserved hypothetical protein. Homology to ne1911 of N. europaea of 67%. InterPro: Glutaredoxin-related protein (IPR004480) TIGR00365: glutaredoxin-related protein no signal peptide no TMHs; Belongs to the glutaredoxin family. Monothiol subfamily.
 
 0.736
iscU
NifU-related protein; A scaffold on which IscS assembles Fe-S clusters. It is likely that Fe-S cluster coordination is flexible as the role of this complex is to build and then hand off Fe-S clusters.

azo1593
Conserved hypothetical protein aminomethyltransferase. Homology to ne1514 of N. europaea of 37% (trembl|Q82UH2) InterPro: Glycine cleavage T-protein (aminomethyl transferase) Tigrfam: gcvT: glycine cleavage system T protein Pfam: Glycine cleavage T-protein This is a family of glycine cleavage T-proteins, part of the glycine cleavage multienzyme complex (GCV) which catalyses the catabolism of glycine. The T-protein is an aminomethyl transferase that catalyses the following reaction: (6S)-tetrahydrofolate + S-aminomethyldihydrolipoylprotein = (6R)-5,10-methylenetetrahydrofolate + NH3 + d [...]

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.
 
  
 0.610
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.
