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

ratAToxic UPF0083 family protein inhibitor of 70S ribosome formation; Toxic component of a type II toxin-antitoxin (TA) system. Binds to 50S ribosomal subunits, preventing them from associating with 30S subunits to form 70S ribosomes and reducing polysomes. It does not cause ribosomes to dissociate however. The antibiotic paromomycin blocks the anti-association activity of RatA. Overexpression results in inhibition of growth in liquid cultures, and in a decrease in protein translation. The other gene of this operon, ratB, is not the cognate antitoxin in this strain; in CFT073 however it do [...] (158 aa)    
Predicted Functional Partners:
ratB
UPF0125 family protein; Does not function as an antitoxin to the upstream RatA toxin; Belongs to the UPF0125 (RnfH) family.
 
  
 0.988
shoB
Toxic membrane protein; Toxic component of a type I toxin-antitoxin (TA) system. May be a toxic protein; overexpression causes cessation of growth and rapid membrane depolarization. Overexpression induces stress-response and a number of membrane protein genes.
      
 0.808
tisB
Toxic membrane persister formation peptide, LexA-regulated; Toxic component of a type I toxin-antitoxin (TA) system (Probable). Overexpression causes cessation of growth, induces stress-response, a number of membrane protein genes, and leads to cell death. Inhibits ATP synthesis, ATP levels drop drastically quickly after induction. Part of the programmed response to DNA damage; damage leads to increased accumulation of the protein which slows or stops bacterial growth, probably allowing DNA repair before cells continue to grow.
      
 0.787
ubiG
Bifunctional 3-demethylubiquinone-9 3-methyltransferase/ 2-octaprenyl-6-hydroxy phenol methylase; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway.
  
  
 0.744
symE
Toxic peptide regulated by antisense sRNA symR; Toxic component of a type I toxin-antitoxin (TA) system. Involved in the degradation and recycling of damaged RNA. It is itself a target for degradation by the ATP-dependent protease Lon. Belongs to the SymE family.
      
 0.690
ubiA
P-hydroxybenzoate octaprenyltransferase; Catalyzes the prenylation of para-hydroxybenzoate (PHB) with an all-trans polyprenyl group. Mediates the second step in the final reaction sequence of ubiquinone-8 (UQ-8) biosynthesis, which is the condensation of the polyisoprenoid side chain with PHB, generating the first membrane-bound Q intermediate 3-octaprenyl-4-hydroxybenzoate. Geranyldiphosphate (GPP), all-trans- farnesyldiphosphate (FPP) and all-trans-solanesyldiphosphate (SPP) are also accepted as side chain precursors. Belongs to the UbiA prenyltransferase family.
  
 
 
 0.675
ubiI
2-octaprenylphenol hydroxylase, FAD-dependent; FAD-dependent monooxygenase required for the aerobic hydroxylation of 2-octaprenylphenol to 2-octaprenyl-6-hydroxy-phenol, the first hydroxylation step in coenzyme Q (ubiquinone) biosynthesis.
  
   
 0.661
sspA
Stringent starvation protein A; Forms an equimolar complex with the RNA polymerase holoenzyme (RNAP) but not with the core enzyme. It is synthesized predominantly when cells are exposed to amino acid starvation, at which time it accounts for over 50% of the total protein synthesized. It is involved in the transition from P1 early to P1 late gene expression. Rnk and SspA can functionally replace P.aeruginosa alginate regulatory gene algR2.
  
    0.646
quuD
DLP12 prophage; Positively regulate expression of some phage genes. Bacterial host RNA polymerase modified by antitermination proteins transcribes through termination sites that otherwise prevent expression of the regulated genes (By similarity); Belongs to the phage antitermination Q type 1 family.
      
 0.645
yefM
Antitoxin of the YoeB-YefM toxin-antitoxin system; Antitoxin component of a type II toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of the YoeB toxin. YefM binds to the promoter region of the yefM-yeoB operon to repress transcription, YeoB acts as a corepressor.
