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:
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)
pqsCPqsC; Required for the biosynthesis of the quorum-sensing signaling molecules 2-heptyl-4(1H)-quinolone (HHQ) and 2-heptyl-3-hydroxy-4(1H)- quinolone (Pseudomonas quinolone signal or PQS), which are important for biofilm formation and virulence. The PqsC/PqsB complex catalyzes the condensation of 2-aminobenzoylacetate (2-ABA) and octanoyl-CoA to form HHQ. First, PqsC acquires an octanoyl group from octanoyl-CoA and forms an octanoyl-PqsC intermediate. Then, together with PqsB, it catalyzes the coupling of 2-ABA with the octanoate group, leading to decarboxylation and dehydration, and re [...] (348 aa)
pqsD3-oxoacyl-[acyl-carrier-protein] synthase III; Required for the biosynthesis of a number of signaling molecules, such as the quinolone signal 2-heptyl-3-hydroxy-4(1H)- quinolone (PQS), 2-heptyl-4-hydroxyquinoline (HHQ) and 2,4- dihydroxyquinoline (DHQ). These molecules are required for normal biofilm formation. Catalyzes the transfer of the anthraniloyl moiety from anthraniloyl-CoA to malonyl-CoA to form 2-aminobenzoylacetyl-CoA. The first step of the reaction is the formation of a covalent anthraniloyl-PqsD intermediate. Next, the short-lived intermediate 3-(2-aminophenyl)- 3-oxopropa [...] (337 aa)
pqsEQuinolone signal response protein; Required for the biosynthesis of the quorum-sensing signaling molecules 2-heptyl-4(1H)-quinolone (HHQ) and 2-heptyl-3-hydroxy-4(1H)- quinolone (Pseudomonas quinolone signal or PQS), which are important for biofilm formation and virulence. Catalyzes the hydrolysis of the intermediate 2-aminobenzoylacetyl-CoA (2-ABA-CoA) to form 2- aminobenzoylacetate (2-ABA), the precursor of HHQ. In vitro, can also hydrolyze other substrates such as S-ethyl-acetothioacetate and acetoacetyl-CoA, but is inactive against anthraniloyl-CoA, malonyl-CoA and octanoyl-CoA. Be [...] (301 aa)
mvfRTranscriptional regulator MvfR; Transcription regulator that plays a critical role in virulence by positively regulating the expression of multiple quorum sensing (QS)-regulated virulence factors, genes involved in protein secretion, translation, response to oxidative stress and the phnAB operon. At the stationary phase, negatively autoregulates its function through cleavage and translocation to the extracellular space ; Belongs to the LysR transcriptional regulatory family. (332 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)
pslAPslA; Class 1: Function experimentally demonstrated in P. aeruginosa. (478 aa)
pelAPelA; Class 1: Function experimentally demonstrated in P. aeruginosa. (948 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)
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)
alg44Alginate biosynthesis protein Alg44; Required for alginate biosynthesis. Belongs to the Alg44 family. (389 aa)
rhlATP-dependent RNA helicase RhlB; DEAD-box RNA helicase involved in RNA degradation. Has RNA- dependent ATPase activity and unwinds double-stranded RNA. Belongs to the DEAD box helicase family. RhlB subfamily. (397 aa)
