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

Your Input:
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)
gyrBDNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner. (806 aa)
exoTProduct name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa). (457 aa)
oprMMajor intrinsic multiple antibiotic resistance efflux outer membrane protein OprM precursor; The outer membrane component of the MexAB-OprM efflux system that confers multidrug resistance. Also functions as the major efflux pump for n-hexane and p-xylene efflux. Over-expression of the pump increases antibiotic and solvent efflux capacities. Can replace the OprJ outer membrane component of the MexCD-OprJ pump; the antibiotics exported are those exported by the intact MexCD pump, showing that efflux substrate specificity is not conferred by this component. Serves as the outer membrane co [...] (485 aa)
catChloramphenicol acetyltransferase; This enzyme is an effector of chloramphenicol (Cm) resistance in bacteria. Acetylates Cm but not 1-acetoxy-Cm. (212 aa)
flgLFlagellar hook-associated protein type 3 FlgL; Product name confidence: Class 2 (High similarity to functionally studied protein). (439 aa)
fliCFlagellin type B; Flagellin is the subunit protein which polymerizes to form the filaments of bacterial flagella. (488 aa)
fliDFlagellar capping protein FliD; Required for the morphogenesis and for the elongation of the flagellar filament by facilitating polymerization of the flagellin monomers at the tip of growing filament.

Essential for motility. Responsible for adhesion to mucin, which is the initial event in colonization by this organism of the airways of cystic fibrosis patients. (474 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)
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)
lasALasA protease precursor; Involved in proteolysis and elastolysis (degradation of the host protein elastin). Has staphylolytic activity (degrades pentaglycine cross-links in cell wall peptidogylcan), preferring Gly- Gly-|-X substrates where X is Ala or Gly. Enhances the elastolytic but not proteolytic activity of elastase (lasB) and elastolytic activity of other proteases. Degradation of host elastin is likely to contribute to the pathogenicity of P.aeruginosa. While either His-317 or His-356 can abstract a proton in the hydrolysis reaction, the same residue performs both functions in a [...] (418 aa)
exoYAdenylate cyclase ExoY; Product name confidence: Class 1 (Function experimentally demonstrated in P. aeruginosa). (378 aa)

Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner. (923 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)
lasBElastase LasB; Cleaves host elastin, collagen, IgG, and several complement components as well as endogenous pro-aminopeptidase. Autocatalyses processing of its pro-peptide.

Primes type IV pili (T4P) assembly and is required for inclusion of minor pilins PilV, PilW and PilX to the surface pili. Stabilizes assembled pilus fibers likely by antagonizing retraction mediated by PilT. Calcium-binding and calcium release by PilY1 seem to be essential for twitching motility and for regulation of pilus retraction dynamics of PilT (By similarity). (1161 aa)

glnEGlutamate-ammonia-ligase adenylyltransferase; Involved in the regulation of glutamine synthetase GlnA, a key enzyme in the process to assimilate ammonia. When cellular nitrogen levels are high, the C-terminal adenylyl transferase (AT) inactivates GlnA by covalent transfer of an adenylyl group from ATP to specific tyrosine residue of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N-terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity. The regulatory region of GlnE binds the signal transd [...] (982 aa)
algPAlginate regulatory protein AlgP; The promoter for a critical alginate biosynthetic gene, AlgD, encoding GDP-mannose dehydrogenase, is activated only under conditions reminiscent of the cystic fibrosis lung (i.e. under high osmolarity), and at least two regulatory genes, AlgP and AlgQ, have been implicated in this activation process.
