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 regulator NrdR; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes. (109 aa)    
Predicted Functional Partners:
KRN59165.1
Replication initiation and membrane attachment protein DnaB.
  
  
 0.901
KRN59164.1
Replicative DNA helicase loader DnaI.
       0.837
cmk
Cytidylate kinase.
      0.750
rpmI
Hypothetical protein; Belongs to the bacterial ribosomal protein bL35 family.
     
 0.731
polA
DNA-directed DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.
     
 0.668
KRN59171.1
UDP-N-acetylmuramate-alanine ligase; Cell wall formation; Belongs to the MurCDEF family.
     
 0.658
coaE
dephospho-CoA kinase; Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A; Belongs to the CoaE family.
  
    0.629
mutM
formamidopyrimidine-DNA glycosylase; Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. Acts as DNA glycosylase that recognizes and removes damaged bases. Has a preference for oxidized purines, such as 7,8-dihydro-8-oxoguanine (8-oxoG). Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-strand break at the site of the removed base with both 3'- and 5'-phosphates.
  
    0.629
rpsU
Hypothetical protein; Belongs to the bacterial ribosomal protein bS21 family.
     
 0.558
infC
Translation initiation factor IF-3; IF-3 binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins.
