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

iscRFe-S cluster assembly transcriptional regulator IscR; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins. (165 aa)    
Predicted Functional Partners:
iscS
IscS subfamily 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.

trmJ
tRNA (cytosine(32)/uridine(32)-2'-O)-methyltransferase TrmJ; Catalyzes the formation of 2'O-methylated cytidine (Cm32) or 2'O-methylated uridine (Um32) at position 32 in tRNA.
      0.834
sufA
Fe-S cluster assembly scaffold SufA; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the HesB/IscA family.
  
  
 0.727
nfuA
Fe-S biogenesis protein NfuA; Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S cluster, can transfer this cluster to apoproteins, and thereby intervenes in the maturation of Fe/S proteins. Could also act as a scaffold/chaperone for damaged Fe/S proteins.
  
  
 0.643
cysG_4
uroporphyrinogen-III C-methyltransferase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme. Belongs to the precorrin methyltransferase family. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family.
     
 0.510
hmp
Nitric oxide dioxygenase; Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and NAD(P)H to convert NO to nitrate, which protects the bacterium from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress; Belongs to the globin family. Two-domain flavohemoproteins subfamily.
     
 0.492
nsrR
Transcriptional repressor NsrR; Negatively regulates the transcription of genes upregulated by nitrosative stress; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
   
 0.476
dnaK_3
Molecular chaperone DnaK; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.414
thiI_2
tRNA 4-thiouridine(8) synthase ThiI; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS.
