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
Your Input:
yoeBToxin 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 [...] (84 aa)
dinJAntitoxin 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 [...] (86 aa)
lacZbeta-D-galactosidase; Protein involved in carbohydrate catabolic process; Belongs to the glycosyl hydrolase 2 family. (1024 aa)
hhaModulator 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 [...] (72 aa)
tomBHha toxicity attenuator; Attenuates Hha toxicity and regulates biofilm formation. Binds to various coding and intergenic regions of genomic DNA. (124 aa)
mdfAMultidrug efflux system protein; Efflux pump driven by the proton motive force. Confers resistance to a broad spectrum of chemically unrelated drugs. Confers resistance to a diverse group of cationic or zwitterionic lipophilic compounds such as ethidium bromide, tetraphenylphosphonium, rhodamine, daunomycin, benzalkonium, rifampicin, tetracycline, puromycin, and to chemically unrelated, clinically important antibiotics such as chloramphenicol, erythromycin, and certain aminoglycosides and fluoroquinolones. Overexpression results in isopropyl-beta-D- thiogalactopyranoside (IPTG) exclusi [...] (410 aa)
ompAOuter membrane protein A (3a;II*;G;d); With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm (Probable). Plays a role in resistance to environmental stress, and a role in outer membrane functionality and cell shape. Non-covalently binds peptidoglycan (Probable). Acts as a porin with low permeability that allows slow penetration of small solutes. A very abundant protein, there can be up to 210,000 OmpA molecules per cell. Reconstitution in unilamellar lipid vesicles shows only about 3% of the protein is in an open conformation, whic [...] (346 aa)
gmrcyclic-di-GMP phosphodiesterase; Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two cyclic-di-GMP (c-di-GMP) control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression of the master biofilm regulator csgD. PdeR acts as a trigger enzyme that connects modules I and II. It inhibits DgcM and MlrA by direct interaction. Inhibition is relieved when PdeR binds and degrades c-di-GMP generated by [...] (661 aa)
yefMAntitoxin 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. (83 aa)
ratBUPF0125 family protein; Does not function as an antitoxin to the upstream RatA toxin; Belongs to the UPF0125 (RnfH) family. (96 aa)
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)
mazFmRNA interferase toxin, antitoxin is MazE; Toxic component of a type II toxin-antitoxin (TA) system. A sequence-specific endoribonuclease it inhibits protein synthesis by cleaving mRNA and inducing bacterial stasis. It is stable, single- strand specific with mRNA cleavage independent of the ribosome, although translation enhances cleavage for some mRNAs. Cleavage occurs at the 5'-end of ACA sequences, yielding a 2',3'-cyclic phosphate and a free 5'-OH, although cleavage can also occur on the 3'-end of the first A. Digests 16S rRNA in vivo 43 nts upstream of the C- terminus; this remove [...] (111 aa)
mazEAntitoxin of the ChpA-ChpR toxin-antitoxin system; Antitoxin component of a type II toxin-antitoxin (TA) system. Labile antitoxin that binds to the MazF endoribonuclease toxin and neutralizes its endoribonuclease activity. Is considered to be an 'addiction' molecule as the cell dies in its absence. Toxicity results when the levels of MazE decrease in the cell, leading to mRNA degradation. This effect can be rescued by expression of MazE, but after 6 hours in rich medium the overexpression of MazF leads to programmed cell death. Cell growth and viability are not affected when MazF and M [...] (82 aa)
mqsAAntitoxin 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 [...] (131 aa)
higAAntitoxinof the HigB-HigA toxin-antitoxin system; Antitoxin component of a type II toxin-antitoxin (TA) system. Functions as an mRNA interferase antitoxin; overexpression prevents HigB-mediated cessation of cell growth and inhibition of cell proliferation. (138 aa)
higBmRNA interferase toxin of the HigB-HigA toxin-antitoxin system; Toxic component of a type II toxin-antitoxin (TA) system. A probable translation-dependent mRNA interferase. Overexpression causes cessation of cell growth and inhibits cell proliferation via inhibition of translation; this blockage is overcome by subsequent expression of antitoxin HigA. Overexpression causes cleavage of a number of mRNAs in a translation-dependent fashion, suggesting this is an mRNA interferase. mRNA interferases play a role in bacterial persistence to antibiotics; overexpression of this protein induces p [...] (104 aa)
