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

PA4431Probable iron-sulfur protein; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. (197 aa)
tatATranslocation protein TatA; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatA could form the protein-conducting channel of the Tat system. (82 aa)
tatBTranslocation protein TatB; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation. (141 aa)
tatCTransport protein TatC; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatB, TatC is part of a receptor directly interacting with Tat signal peptides. (267 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)
pqsAProbable coenzyme A ligase; Catalyzes the formation of anthraniloyl-CoA, which is the priming step for entry into the Pseudomonas quinolone signal (PQS) biosynthetic pathway. Also active on a variety of aromatic substrates, including benzoate and chloro and fluoro derivatives of anthranilate. (517 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)
phzA2Probable phenazine biosynthesis protein; Involved in the biosynthesis of the antibiotic phenazine, a nitrogen-containing heterocyclic molecule having important roles in virulence, competition and biological control. PhzA2 (operon phzA2B2C2E2F2G2) has a role in the biosynthesis of the phenazine during both planktonic growth and biofilm development, and in host infection during biofilm development. (162 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)
rhlARhamnosyltransferase chain A; Required for rhamnolipid surfactant production. Supplies the acyl moieties for rhamnolipid biosynthesis by competing with the enzymes of the type II fatty acid synthase (FASII) cycle for the beta-hydroxyacyl-acyl carrier protein (ACP) pathway intermediates. Catalyzes the formation of one molecule of beta-hydroxydecanoyl-beta-hydroxydecanoate from two molecules of beta- hydroxydecanoyl-ACP. Is the only enzyme required to generate the lipid component of rhamnolipid. In vitro results establish that RhlA is highly selective for 10-carbon acyl-ACP intermediates [...] (295 aa)
