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 repressor of deoxyribonucleotide biosynthesis NrdR; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (149 aa)    
Predicted Functional Partners:
ribD
Diaminohydroxyphosphoribosylaminopyrimidine deaminase; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
 
  
 0.942
birA
Bifunctional biotin operon repressor/biotin-[acetyl-CoA-carboxylase] ligase BirA; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.
     
 0.887
nusB
Transcription antitermination factor NusB; Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons.
   
 0.884
thiL
Thiamine-phosphate kinase ThiL; Catalyzes the ATP-dependent phosphorylation of thiamine- monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1; Belongs to the thiamine-monophosphate kinase family.
    
 0.852
argR
Arginine-responsive transcriptional repressor of arginine metabolism ArgR; Regulates arginine biosynthesis genes.
   
  
 0.839
ribBA
Bifunctional 34-dihydroxy-2-butanone 4-phosphate synthase/GTP cyclohydrolase II RibBA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family.
     
 0.813
nrtR
Transcriptional repressor of nicotinamide riboside utilization NrtR.
  
  
 0.807
ribE
Riboflavin synthase beta subunit RibE; Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2- butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin; Belongs to the DMRL synthase family.
 
  
 0.791
cmk
Cytidylate kinase Cmk.
      0.700
hexR
RpiR family transcriptional regulator, carbohydrate utilization regulator; 2-keto-3-deoxy-6-phosphogluconate-responsive transcriptional regulator of central carbohydrate metabolism HexR.
