STRINGSTRING
STRING protein interaction network
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

pqqGPyrroloquinoline quinone biosynthesis protein PqqB; May be involved in the transport of PQQ or its precursor to the periplasm; Belongs to the PqqB family. (303 aa)    
Predicted Functional Partners:
pqqC
Pyrroloquinoline-quinone synthase; 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.
  
 0.997
pqqD
Pyrroloquinoline quinone biosynthesis protein D.
 
  
 0.976
pqqE
Pyrroloquinoline quinone biosynthesis protein PqqE; 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).
 
  
 0.976
adhA
PQQ-dependent alcohol dehydrogenase.
  
  
 0.647
duf6
Protein of unknown function DUF6, transmembrane.
       0.563
pqqA
Hypothetical protein predicted by Glimmer/Critica; Required for coenzyme pyrroloquinoline quinone (PQQ) biosynthesis. PQQ is probably formed by cross-linking a specific glutamate to a specific tyrosine residue and excising these residues from the peptide; Belongs to the PqqA family.
       0.542
AGA_622
Peptidase S9 prolyl oligopeptidase active site domain protein.
  
  
 0.541
phnA
Phosphonoacetate hydrolase.
     
 0.428
