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.

nrdGAnaerobic ribonucleotide reductase activator 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. (240 aa)    
Predicted Functional Partners:
nrdD
Anaerobic ribonucleoside-triphosphate reductase.
 
 
 0.997
folKE
2-Amino-4-hydroxy-6- hydroxymethyldihydropteridinepyrophosphokinase / GTP cyclohydrolase I.
  
  
 0.672
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
     
 0.663
rnhB
Ribonuclease HII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
     
 0.537
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
     
 0.515
tyrS
Tyrosyl-tRNA synthetase; Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr); Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 1 subfamily.
     
 0.459
parE
DNA topoisomerase IV, subunit B; Topoisomerase IV is essential for chromosome segregation. It relaxes supercoiled DNA. Performs the decatenation events required during the replication of a circular DNA molecule; Belongs to the type II topoisomerase family. ParE type 2 subfamily.
     
 0.435
addA
ATP-dependent deoxyribonuclease subunit A; The heterodimer acts as both an ATP-dependent DNA helicase and an ATP-dependent, dual-direction single-stranded exonuclease. Recognizes the chi site generating a DNA molecule suitable for the initiation of homologous recombination. The AddA nuclease domain is required for chi fragment generation; this subunit has the helicase and 3' -> 5' nuclease activities; Belongs to the helicase family. AddA subfamily.
     
 0.422
rlmH
Conserved hypothetical protein; Specifically methylates the pseudouridine at position 1915 (m3Psi1915) in 23S rRNA; Belongs to the RNA methyltransferase RlmH family.
   
    0.413
nrdR
Conserved hypothetical protein; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family.
     
 0.405
