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

nrdRNrdR family transcriptional regulator; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes. (121 aa)    
Predicted Functional Partners:
NrdA
Vitamin B12-dependent ribonucleotide reductase; 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.
     
 0.903
RAM_36280
COG1985 Pyrimidine reductase, riboflavin biosynthesis.
  
  
 0.811
NrdA-2
Ribonucleoside-diphosphate reductase alpha chain; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
     
 0.753
cobN
Cobaltochelatase subunit CobN; COG1429 Cobalamin biosynthesis protein CobN and related Mg-chelatases.
      
 0.728
ribBA
GTP cyclohydrolase II/3,4-dihydroxy 2-butanone 4-phosphate synthase; 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.
     
 0.677
lexA-2
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.
 
   
 0.655
lexA
LexA family transcriptional regulator; 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.
 
   
 0.650
NrdB
Ribonucleotide-diphosphate reductase subunit beta; 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.
     
 0.605
CobO
cob(I)alamin adenolsyltransferase/cobinamide ATP-dependent adenolsyltransferase; COG2109 ATP:corrinoid adenosyltransferase.
     
 0.563
Ssb
COG0629 Single-stranded DNA-binding protein.
 
   
 0.551
