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

nrdRConserved hypothetical protein; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (164 aa)    
Predicted Functional Partners:
dnaB
Chromosome replication initiation / membrane attachment protein DnaB.
  
  
 0.879
birA
biotin--acetyl-CoA-carboxylase ligase; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
     
 0.862
dnaI
Primosome component (helicase loader) DnaI.
       0.800
argR-2
Transcriptional repressor protein, putative; Regulates arginine biosynthesis genes.
      
 0.770
argR
Arginine repressor; Regulates arginine biosynthesis genes.
      
 0.765
guaB
Inosine monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
     
 0.656
der
Phosphoglycerate dehydrogenase-related protein; GTPase that plays an essential role in the late steps of ribosome biogenesis; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. EngA (Der) GTPase family.
     
 0.601
adcR
Zinc transport transcriptional repressor.
      
 0.594
prsA1
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P); Belongs to the ribose-phosphate pyrophosphokinase family. Class I subfamily.
     
 0.580
rr01
