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:
rsmARsmA, regulator of secondary metabolites; A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability. Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems. Usually binds in the 5'-UTR; binding at or near the Shine-Dalgarno sequence prevents ribosome-binding, repressing translation, binding elsewhere in the 5'-UTR can activate translation and/or stabilize the mRNA. Its function is antagonized by small RNA(s). Probably [...] (61 aa)
lasRTranscriptional regulator LasR; Transcriptional activator of elastase structural gene (LasB). Binds to the PAI autoinducer; Belongs to the autoinducer-regulated transcriptional regulatory protein family. (239 aa)
rsaLRegulatory protein RsaL; Product name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa). (80 aa)
rhlRTranscriptional regulator RhlR; Necessary for transcriptional activation of the rhlAB genes encoding the rhamnosyltransferase. It also functions as a transcriptional activator of elastase structural gene (lasB). Binds to autoinducer molecules BHL (N-butanoyl-L-homoserine lactone), and HHL (N-hexanoyl-L-homoserine lactone). (241 aa)
rhlIAutoinducer synthesis protein RhlI; Required for the synthesis of BHL (N-butanoyl-L-homoserine lactone), and HHL (N-hexanoyl-L-homoserine lactone) autoinducer molecules which bind to RhlR and thus acts in elastase biosynthesis regulation. (201 aa)
pqsHProbable FAD-dependent monooxygenase; Involved in the terminal step of the biosynthesis of quinolone which in addition to serve as a potent signal for quorum sensing, chelates iron and promotes the formation of membrane vesicles (MVs). Catalyzes the hydroxylation of 2-heptyl-4-quinolone (C7-HHQ) to yield 2-heptyl-3-hydroxy-4-quinolone (PQS). Belongs to the 3-hydroxybenzoate 6-hydroxylase family. (382 aa)
pvdQ3-oxo-C12-homoserine lactone acylase PvdQ; Catalyzes the deacylation of acyl-homoserine lactone (AHL or acyl-HSL), releasing homoserine lactone (HSL) and the corresponding fatty acid. Possesses a specificity for the degradation of long-chain acyl-HSLs (side chains of 11 to 14 carbons in length). Degrades 3-oxo- C12-HSL, one of the two main AHL signal molecules of P.aeruginosa, and thereby functions as a quorum quencher, inhibiting the las quorum- sensing system. Therefore, may enable P.aeruginosa to modulate its own quorum-sensing-dependent pathogenic potential. Also appears to be requ [...] (762 aa)
vqsMAraC-type transcriptional regulator VqsM; Transcriptional regulator involved in both the repression (at least 99 genes, such as mexR and algU) and in the activation (at least 203 genes, such as mvfR, rsaL, vqsR and rpoS) of regulatory or putative regulatory proteins which are implicated in quorum sensing, virulence and multidrug resistance. (325 aa)
qscRQuorum-sensing control repressor; Product name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa). (237 aa)
lasIAutoinducer synthesis protein LasI; Required for the synthesis of PAI consisting of 3-oxo-N- (tetrahydro-2-oxo-3-furanyl)-dodecanamide also known as N-(3- oxododecanoyl)homoserine lactone, an autoinducer molecule which binds to LasR and thus acts in elastase biosynthesis regulation. (201 aa)
quiPQuiP; Catalyzes the deacylation of acyl-homoserine lactone (AHL or acyl-HSL), releasing homoserine lactone (HSL) and the corresponding fatty acid. Possesses a specificity for the degradation of long-chain acyl-HSLs (side chains of seven or more carbons in length). Appears to be the acyl-HSL acylase that underlies the ability of P.aeruginosa to degrade and utilize certain acyl-HSLs as growth nutrients, including one of its own quorum signals, 3-oxo-C12-HSL. Is thought to have a role in quorum quenching; Belongs to the peptidase S45 family. (847 aa)
crcCatabolite repression control protein; Product name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa). (259 aa)
ppxExopolyphosphatase; Degradation of inorganic polyphosphates (polyP). Releases orthophosphate processively from the ends of the polyP chain. Has also polyphosphate:ADP phosphotransferase activity, catalyzing the production of ATP from ADP and polyP. (506 aa)
fabYProbable beta-ketoacyl synthase; Involved in the initiation of the fatty acid biosynthesis. Catalyzes the condensation of acetyl coenzyme A (acetyl-CoA) with malonyl-acyl carrier protein (ACP) to make the fatty acid synthesis (FAS) primer beta-acetoacetyl-ACP. It can also use short-chain acyl-CoA as substrates, including butyryl-CoA, and hexanoyl-CoA, but does not use any of the longer chain acyl-CoA substrates. Belongs to the thiolase-like superfamily. Beta-ketoacyl-ACP synthases family. (634 aa)
hfqHfq; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family. (82 aa)
