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; Belongs to the NrdR family. (149 aa)    
Predicted Functional Partners:
ftsA
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.
     
 0.721
CPF_2013
PRC-barrel domain protein; Identified by match to protein family HMM PF05239; match to protein family HMM TIGR02888.
       0.697
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.
     
 0.694
spoIIGA
Sporulation factor SpoIIGA; 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.
     
 0.664
ribD
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.
  
  
 0.621
CPF_2011
Conserved hypothetical protein; Identified by similarity to PIR:F97109; match to protein family HMM PF02578; Belongs to the multicopper oxidase YfiH/RL5 family.
       0.608
CPF_2010
Sensory box histidine kinase; Identified by match to protein family HMM PF00512; match to protein family HMM PF00672; match to protein family HMM PF00989; match to protein family HMM PF02518; match to protein family HMM TIGR00229.
       0.600
sigG
RNA polymerase sigma-G factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released.
     
 0.559
spoIIAB
Anti-sigma F factor; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
      
 0.555
ribA
Riboflavin biosynthesis protein RibA; 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.
