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

nrdDAnaerobic ribonucleoside-triphosphate reductase; Catalyzes the conversion of ribonucleotides into deoxyribonucleotides, which are required for DNA synthesis and repair. Belongs to the anaerobic ribonucleoside-triphosphate reductase family. (712 aa)    
Predicted Functional Partners:
nrdG
Anaerobic ribonucleotide reductase activating protein; Activation of anaerobic ribonucleoside-triphosphate reductase under anaerobic conditions by generation of an organic free radical, using S-adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine; Belongs to the organic radical-activating enzymes family.
 
 
 0.998
nrdB
Ribonucleoside-diphosphate reductase 1, beta subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R2 contains the tyrosyl radical required for catalysis; Belongs to the ribonucleoside diphosphate reductase small chain family.
  
  
 0.933
dut
Deoxyuridinetriphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family.
    
 0.918
cyaA
Adenylate cyclase. (SW:CYAA_SALTY).
  
  
  0.917
nrdA
Ribonucleoside diphosphate reductase 1, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide; Belongs to the ribonucleoside diphosphate reductase large chain family.
  
  
 0.915
nrdI
Stimulates ribonucleotide reduction; Probably involved in ribonucleotide reductase function.
     
 0.913
pykF
Pyruvate kinase I; Formerly F; fructose stimulated; pyruvate kinase I. (SW:KPY1_SALTY).
   
 
  0.911
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
     
 0.911
pyrG
CTP synthetase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
   
 
 0.907
dcd
dUTPase; Catalyzes the deamination of dCTP to dUTP.
    
 0.902
