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.

nrdRTranscriptional regulator NrdR; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (188 aa)    
Predicted Functional Partners:
EFL38708.1
Ribonucleoside-diphosphate reductase, adenosylcobalamin-dependent; Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen.
     
 0.837
EFL40561.1
Riboflavin/cytosine deaminase.
  
  
 0.788
ribBA
3,4-dihydroxy-2-butanone-4-phosphate synthase/GTP cyclohydrolase II; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
    
 0.771
lexA
LexA repressor; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.
 
   
 0.660
EFL39209.1
Ribonucleoside-diphosphate reductase, beta subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides; Belongs to the ribonucleoside diphosphate reductase small chain family.
     
 0.574
EFL38706.1
Conserved hypothetical protein.
       0.540
EFL42077.1
Cobaltochelatase, CobN subunit.
      
 0.506
EFL38882.1
Phosphomethylpyrimidine kinase.
   
    0.490
EFL42075.1
cob(I)yrinic acid a,c-diamide adenosyltransferase.
     
 0.449
dcd
Deoxycytidine triphosphate deaminase; Bifunctional enzyme that catalyzes both the deamination of dCTP to dUTP and the hydrolysis of dUTP to dUMP without releasing the toxic dUTP intermediate.
  
 
  0.428
