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:
lmo2553Phosphatidylglycerol lysyltransferase; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms. (356 aa)
tufAElongation factor Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis. (395 aa)
inlBInternalin B; Mediates the entry of L.monocytogenes into normally non- phagocytic mammalian host cells. Its host receptor is hepatocyte growth factor receptor (HGF receptor, a tyrosine kinase, MET) which is tyrosine-phosphorylated in response to InlB. Downstream targets MAPK1/MAPK3 (Erk1/2) and AKT are phosphorylated in response to InlB, which also causes cell colony scattering. Complement component 1 Q subcomponent-binding protein (gC1q-R, C1QBP) has been suggested to also act an InlB receptor, but this is less certain. Stimulation of Tyr-phosphorylation of MET by InlB is potentiated [...] (630 aa)
eutBEutB protein; Similar to ethanolamine ammonia-lyase, heavy chain. (454 aa)
eutCSimilar to ethanolamine ammonia-lyase, light chain; Belongs to the EutC family. (293 aa)
lmo1695Phosphatidylglycerol lysyltransferase; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms. (865 aa)
lmo1702Fosfomycin resistance protein FosX; Catalyzes the hydration of fosfomycin. Belongs to the fosfomycin resistance protein family. (133 aa)
inlCInternalin C. (296 aa)
lmo2185Hemin/hemoglobin-binding protein 2; Acts as an extracellular and cell wall-bound hemophore; scavenges host heme and hemoglobin from the environment and also serves as a cell wall receptor for both (Probable). At low hemin (Hn) and hemoglobin (Hb) concentrations adsorbs Hn/Hb and presumably directs it to membrane transporters (Probable). Soluble Hbp2 can probably pass Hn/Hb to cell wall-anchored Hbp2, and both forms can accept Hn/Hb from Hbp1. May be involved in crossing the digestive barrier in infected animals. Binds host hemin (Probable). Binds host hemoglobin with affinity in the na [...] (569 aa)
lmo2186Hemin/hemoglobin-binding protein 1; Binds both host hemin and hemoglobin with affinity in the nanomolar range and presumably directs it to membrane transporters. (207 aa)
lmo2219Foldase protein PrsA 2; Plays a major role in protein secretion by helping the post- translocational extracellular folding of several secreted proteins. (293 aa)
gtcAWall teichoic acid glycosylation protein GtcA; Involved in the decoration of cell wall teichoic acid with galactose and glucose; Belongs to the GtrA family. (145 aa)
plcAPhosphatidylinositol-specific phospholipase c; Cleaves glycosylphosphatidylinositol (GPI) and phosphatidylinositol (PI) anchors but not PI phosphates. Important factor in pathogenesis, PI-PLC activity is present only in virulent listeria species. It may participate in the lysis of the phagolysosomal membrane. (317 aa)
hlyListeriolysin O precursor; Sulfhydryl-activated pore-forming toxin, which is a major virulence factor required for the escape of bacteria from phagosomal vacuoles and entry into the host cytosol. After binding to target membranes, the protein undergoes a major conformation change, leading to its insertion in the host membrane and formation of an oligomeric pore complex. Listeriolysin O activates mitogen-activated protein (MAP) kinase activity in host cells, most likely as a result of the permeabilization of the host cell membrane. Also induces a proteasome- independent degradation of U [...] (529 aa)
mplZinc metalloproteinase precursor; Probably linked to the pathogenesis of listerial infection; Belongs to the peptidase M4 family. (510 aa)
actAActin-assembly inducing protein precursor; Virulence factor required for host cell microfilament interaction. It induces actin assembly around the bacteria to allow it to move within the cytoplasm. It is involved in the actin polymerization process. It seems to act as a nucleator that induces the reorganization of the actin cytoskeleton. (639 aa)
plcBPhospholipase C; Important role in the infectious process. May contribute to efficient lysis of the two-membrane vacuoles that surround the bacteria after direct cell-to-cell spread. (289 aa)
inlAInternalin A; Mediates the entry of L.monocytogenes into host intestinal epithelial cells; transformation with inlA alone allows L.innocua (a non-invasive species) to be taken up by host cells. Binds to human receptor cadherin-1 (E-cadherin, CDH1); the chicken homolog of cadherin-1 but not cadherin- 2 function as receptors. Mouse cadherin-1 is not a receptor, however mutating a single surface-exposed residue (Glu-172 to Pro in mouse) allows cadherin-1 to act as a receptor for InlA ; Belongs to the internalin family. (800 aa)
