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

pqqFPyrroloquinoline quinone biosynthesis protein F; Required for coenzyme pyrroloquinoline quinone (PQQ) biosynthesis. It is thought that this protein is a protease that cleaves peptides bond in a small peptide (gene pqqA), providing the glutamate and tyrosine residues which are necessary for the synthesis of PQQ (By similarity). (775 aa)    
Predicted Functional Partners:
pqqH
PqqH; 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).
  
  
 0.916
pqqB
Pyrroloquinoline quinone biosynthesis protein B; May be involved in the transport of PQQ or its precursor to the periplasm; Belongs to the PqqB family.
  
  
 0.915
pqqD
Pyrroloquinoline quinone biosynthesis protein D; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway.
  
  
 0.915
pqqE
Pyrroloquinoline quinone biosynthesis protein E; Catalyzes the cross-linking of a glutamate residue and a tyrosine residue in the PqqA protein as part of the biosynthesis of pyrroloquinoline quinone (PQQ).
 
  
 0.914
pqqC
Pyrroloquinoline quinone biosynthesis protein C; Ring cyclization and eight-electron oxidation of 3a-(2-amino- 2-carboxyethyl)-4,5-dioxo-4,5,6,7,8,9-hexahydroquinoline-7,9- dicarboxylic-acid to PQQ.
  
  
 0.903
PA1955
Hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).
   
  
 0.768
exaA
Quinoprotein ethanol dehydrogenase; Catalyzes the oxidation of primary alcohols to the corresponding aldehydes, except for methanol, which is a very poor substrate. ExaA is also able to use secondary alcohols as well as amino alcohols like ethanolamine and l-amino-2-propanol, and aldehydes as substrates; Belongs to the bacterial PQQ dehydrogenase family.
   
  
 0.619
exaB
Cytochrome c550; Is an essential component of the ethanol oxidation system that allows P.aeruginosa to grow on ethanol as the sole carbon and energy source. Is the direct electron acceptor of the quinoprotein ethanol dehydrogenase (QEDH).
  
  
 0.618
PA1974
Hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).
  
  
 0.599
PA1972
Conserved hypothetical protein; Product name confidence: Class 4 (Homologs of previously reported genes of unknown function, or no similarity to any previously reported sequences).
