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:
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.

Catalyzes the oxidative decarboxylation of 5-methylphenazine-1-carboxylate (5-methyl- PCA) to pyocyanine. Can also act on phenazine-1-carboxylate (PCA), converting it into 1-hydroxyphenazine (1-HP). However, PCA is a poor substrate. (402 aa)
phzMProbable phenazine-specific methyltransferase; Involved in the biosynthesis of pyocyanine, a blue-pigmented phenazine derivative, which plays a role in virulence.

Cation-independent O-methyltransferase family. (334 aa)
lasBElastase LasB; Cleaves host elastin, collagen, IgG, and several complement components as well as endogenous pro-aminopeptidase. Autocatalyses processing of its pro-peptide. Processes the pro-peptide of pro-chitin-binding protein (cbpD). Involved in the pathogenesis of P.aeruginosa infections. (498 aa)
lecBFucose-binding lectin PA-IIL; Product name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa). (115 aa)
PA3328Probable FAD-dependent monooxygenase; Product name confidence: Class 3 (Function proposed based on presence of conserved amino acid motif, structural feature or limited sequence similarity to an experimentally studied gene). (388 aa)
fabVHypothetical protein; Involved in the final reduction of the elongation cycle of fatty acid synthesis (FAS II). Catalyzes the reduction of a carbon- carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). It can use both crotonyl-CoA and trans-2- decenoyl-ACP. It is able to convert trans-2-enoyl-ACP of different length (C2 to C16) to the corresponding acyl-ACP. Belongs to the TER reductase family. (398 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)
lecALecA; D-galactose specific lectin. Binds in decreasing order of affinity: melibiose, methyl-alpha-D-galactoside, D-galactose, methyl- beta-D-galactoside, N-acetyl-D-galactosamine. Similar to plant lectins in its selective (carbohydrate-specific) hemagglutinating activity; Belongs to the LecA/PllA lectin family. (122 aa)
chiCChitinase; Product name confidence: Class 2 (High similarity to functionally studied protein); Belongs to the glycosyl hydrolase 18 family. (483 aa)
fabINADH-dependent enoyl-ACP reductase; Catalyzes the reduction of a carbon-carbon double bond in an enoyl moiety that is covalently linked to an acyl carrier protein (ACP). Involved in the elongation cycle of fatty acid which are used in the lipid metabolism (By similarity); Belongs to the short-chain dehydrogenases/reductases (SDR) family. FabI subfamily. (265 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)
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)
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)
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)
pqsBPqsB; 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. PqsB, together with PqsC, catalyzes the coupling of 2-ABA with the octanoate group, leading to decarboxylation and dehydration, and resulting in closure of the quinoline ring. PqsB is probably required for the proper folding of PqsC ra [...] (283 aa)
