STRING protein interaction network
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:
some 3D structure is known or predicted
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
protein homology
Your Input:
Gene Fusion
aprAAlkaline metalloproteinase precursor; Belongs to the peptidase M10B family (479 aa)    
Predicted Functional Partners:
Alkaline proteinase inhibitor; Inhibitor of the alkaline protease. It forms a non-covalent bond with the protease and may prevent its autocatalytic cleavage in the periplasm (By similarity)
Type i secretion membrane fusion , hlyd family protein; Involved in the secretion of alkaline protease
Type i secretion outer membrane , tolc family protein; Involved in the secretion of alkaline protease
Atp-binding cassette, subfamily c, bacterial exporter for protease/lipase; Involved in the secretion of alkaline protease
Hypothetical protein; Uncharacterized protein
Pseudolysin; 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
type_I_hlyD: type I secretion membrane fusion , HlyD family protein
Lasa 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 [...]
Acyl homoserine lactone synthase; 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
Exotoxin a precursor; An NAD-dependent ADP-ribosyltransferase (ADPRT). Catalyzes the transfer of the ADP ribosyl moiety of oxidized NAD (NAD(+)) onto eukaryotic elongation factor 2 (eEF-2) thus arresting protein synthesis. Has an LD(50) of 65 ng/ml against the human lung epithelial cell line C38
