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:
some 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

ratBPutative component of the rsx system; Does not function as an antitoxin to the upstream RatA toxin (96 aa)    
Predicted Functional Partners:
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 [...]

ybeU
DUF1266 domain-containing protein YbeU; To E.coli YbeR

rsxB
Na+-translocating ferredoxin:nad+ oxidoreductase subunit b; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane (By similarity). Required to maintain the reduced state of SoxR. Probably transfers electron from NAD(P)H to SoxR
 
   
 0.748
smpB
Required for rescue of stalled ribosomes mediated by trans- translation. Binds to tmRNA RNA (also known as SsrA or 10Sa RNA, 363 nucleotides in this organism), required for stable binding of tmRNA to ribosomes . tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB (Probable). tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. Able to recruit charged tmRNA to ribosomes . Does not play a role in transcription, processing or Ala-aminoacylation of tmRNA . Other stu [...]

tomB
Protein that modulates hha toxicity; Attenuates Hha toxicity and regulates biofilm formation. Binds to various coding and intergenic regions of genomic DNA
      
 0.677
rsxG
Na+-translocating ferredoxin:nad+ oxidoreductase subunit g; Part of a membrane-bound complex that couples electron transfer with translocation of ions across the membrane (By similarity). Required to maintain the reduced state of SoxR. Probably transfers electron from NAD(P)H to SoxR

yefM
Yefm antitoxin of the yoeb-yefm toxin-antitoxin pair and dna binding transcriptional repressor; 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
      
 0.613
yoeB
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, YeoB acts as a corepressor. Also shown in vit [...]

rzpD
DLP12 prophage; putative prophage endopeptidase RzpD; 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)

hha
Haemolysin expression modulating protein; 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 [...]
