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

mcbRColanic acid and biofilm gene transcriptional regulator, MqsR-controlled; Important for biofilm formation. Represses expression of McbA by binding to its promoter region, which prevents colanic acid overproduction and mucoidy. (221 aa)    
Predicted Functional Partners:
mqsR
GCU-specific mRNA interferase toxin of the MqsR-MqsA toxin-antitoxin system; Toxic component of a type II toxin-antitoxin (TA) system. Plays a significant role in the control of biofilm formation and induction of persister cells in the presence of antibiotics. An mRNA interferase which has been reported to be translation-independent. It has also been reported to be translation-dependent. Cleavage has been reported to occur on either side of G in the sequence GCU. Also reported to cleave after C in GC(A/U) sequences. There are only 14 genes in E.coli W3110 (and probably also MG1655) tha [...]

prmB
N5-glutamine methyltransferase; Specifically methylates the 50S ribosomal protein L3 on 'Gln- 150'. Does not methylate the translation termination release factors RF1 and RF2; Belongs to the protein N5-glutamine methyltransferase family. PrmB subfamily.
    
   0.775
rspR
Transcriptional repressor for rspAB; Repressor of the rspAB operon. Acts by binding directly to the upstream region of rspA.
  
     0.767
yieP
Putative transcriptional regulator.
  
  
 0.705
yciG
KGG family protein; Belongs to the con-10 family.
   
  
 0.659
csiR
Transcriptional repressor of csiD; Negatively regulates the expression of the glaH-lhgD-gabDTP operon in a temporal manner during entry into stationary phase or during the first few hours of carbon starvation. Thereby is involved in the regulation of a L-lysine degradation pathway that proceeds via cadaverine, glutarate and L-2- hydroxyglutarate. Binds to two primary and two secondary sites in the promoter region of the glaH operon with the consensus sequences TTGTN5TTTT and ATGTN5TTTT of the primary sites, each separated by six nucleotides.
  
    0.659
dgoR
D-galactonate catabolism operon transcriptional repressor; Repressor for the dgoRKAT operon. Binds D-galactonate as an inducer.
  
  
 0.637
yciF
Putative structural proteins.
   
  
 0.630
mcbA
Colanic acid mucoidy stimulation protein; Affects biofilm formation and mucoidy.
      
 0.628
mqsA
Antitoxin for MqsR toxin; Antitoxin component of a type II toxin-antitoxin (TA) system. Labile antitoxin that binds to the MqsR mRNA interferase toxin and neutralizes its endoribonuclease activity. Overexpression prevents MqsR-mediated cessation of cell growth and inhibition of cell proliferation. Initially reported to act as a cotranscription factor with MqsA. Following further experiments, the MqsR-MqsA complex does not bind DNA and all reported data are actually due to a small fraction of free MqsA alone binding DNA. Addition of MqsR to a preformed MqsA-promoter DNA complex causes d [...]
