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. (167 aa)    
Predicted Functional Partners:
ribD_2
Riboflavin biosynthesis protein RibD; 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.
  
  
 0.850
OOM74156.1
PRC-barrel domain protein.
       0.837
spoIIGA
Sporulation sigma-E factor-processing peptidase; Probable aspartic protease that is responsible for the proteolytic cleavage of the RNA polymerase sigma E factor (SigE/spoIIGB) to yield the active peptide in the mother cell during sporulation. Responds to a signal from the forespore that is triggered by the extracellular signal protein SpoIIR. Belongs to the peptidase U4 family.
     
 0.787
sigF_2
RNA polymerase sigma-F factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
     
 0.775
ribBA_1
Riboflavin biosynthesis protein RibBA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
    
 0.769
ribBA_2
Riboflavin biosynthesis protein RibBA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
    
 0.769
ftsA_2
Cell division protein FtsA; Cell division protein that is involved in the assembly of the Z ring. May serve as a membrane anchor for the Z ring. Belongs to the FtsA/MreB family.
     
 0.748
ftsZ
Cell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
     
 0.747
sigE
RNA polymerase sigma-E factor precursor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
       0.667
nrdE2
Ribonucleoside-diphosphate reductase subunit alpha 2; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
     
 0.652
