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

tomBHha toxicity attenuator; Attenuates Hha toxicity and regulates biofilm formation. Binds to various coding and intergenic regions of genomic DNA. (124 aa)    
Predicted Functional Partners:
hha
Modulator of gene expression, with H-NS; Down-regulates hemolysin (hly) expression in complex with H- NS. Stimulates transposition events in vivo. Modifies the set of genes regulated by H-NS; Hha and Cnu (YdgT) increase the number of genes DNA bound by H-NS/StpA and may also modulate the oligomerization of the H-NS/StpA-complex. Binds DNA and influences DNA topology in response to environmental stimuli; does not however interact with DNA in the absence of H-NS. Involved in persister cell formation, acting downstream of mRNA interferase (toxin) MqsR. Decreases biofilm formation by repre [...]

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.
   
  
 0.793
ratB
UPF0125 family protein; Does not function as an antitoxin to the upstream RatA toxin; Belongs to the UPF0125 (RnfH) family.
      
 0.736
yoeB
Toxin of the YoeB-YefM toxin-antitoxin system; Toxic component of a type II toxin-antitoxin (TA) system. Its mode of function is controversial; it has been proposed to be an mRNA interferase but also an inhibitor of translation initiation. When overproduced in wild-type cells, inhibits bacterial growth and translation by cleavage of mRNA molecules while it has a weak effect on colony forming ability. Overproduction of Lon protease specifically activates YoeB-dependent mRNA cleavage, leading to lethality. YefM binds to the promoter region of the yefM-yeoB operon to repress transcription [...]

maa
Maltose O-acetyltransferase; Catalyzes the CoA-dependent transfer of an acetyl group to maltose and other sugars. Acetylates glucose exclusively at the C6 position and maltose at the C6 position of the non-reducing end glucosyl moiety. Is able to acetylate maltooligosaccharides ; Belongs to the transferase hexapeptide repeat family.

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 [...]

rzpD
DLP12 prophage; Necessary for host cell lysis. It is believed to code for an endopeptidase that cleaves the amino-carboxyl cross-link between the diaminopimelic acid and D-alanine residues in the murein component of the bacterial cell wall (By similarity).
      
 0.621
yfjZ
CP4-57 prophage; Antitoxin component of a type IV toxin-antitoxin (TA) system. Antitoxin that counteracts the effect of cognate toxin YpjF. Also counteracts the effect of non-cognate toxins CbtA and YfkI.
      
 0.621
ratA
Toxic 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 [...]

dinJ
Antitoxin of YafQ-DinJ toxin-antitoxin system; Antitoxin component of a type II toxin-antitoxin (TA) system. A labile antitoxin that counteracts the effect of cognate toxin YafQ. YafQ and DinJ together bind their own promoter, and repress its expression. There are 2 operators with imperfect inverted repeats (IR) in the dinJ promoter, YafQ-(DinJ)2-YafQ only binds to the first (most upstream) of them to repress transcription; binding to a single IR is sufficient for activity in vivo and in vitro. DinJ alone is as potent a transcriptional repressor as the heterotetramer and also only need [...]
