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

nrdRTranscriptional repressor nrdR; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (155 aa)    
Predicted Functional Partners:
ribD
Riboflavin biosynthesis protein; 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.
 
  
 0.969
cmk
Cytidylate kinase EC:2.7.4.14 catalyses the phosphorylation of cytidine 5-monophosphate (dCMP) to cytidine 5-diphosphate (dCDP) in the presence of ATP or GTP, Reaction: ATP + (d)CMP <=> ADP + (d)CDP.
      0.723
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
  
  
 0.655
ribB
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; Belongs to the DHBP synthase family.
     
 0.634
Dshi_2258
Conserved hypothetical protein; PFAM: protein of unknown function UPF0047 KEGG: sit:TM1040_2137 protein of unknown function UPF0047.
  
    0.609
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.
 
   
 0.577
nadE
Glutamine-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.490
cobL
Decarboxylating precorrin-6Y C(5,15)-methyltransferase; KEGG: ava:Ava_3558 uroporphyrin-III C/tetrapyrrole (corrin/porphyrin) methyltransferase TIGRFAM: precorrin-6y C5,15-methyltransferase (decarboxylating), CbiE subunit; precorrin-6Y C5,15-methyltransferase (decarboxylating), CbiT subunit PFAM: Uroporphyrin-III C/tetrapyrrole (Corrin/Porphyrin) methyltransferase.
      
 0.477
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
     
 0.462
rpoD
RNA polymerase sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.
 
  
 0.461
