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.

pqqCPyrroloquinoline 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. (251 aa)    
Predicted Functional Partners:
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.
  
 0.998
pqqD
Pyrroloquinoline quinone biosynthesis protein PqqD; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway.
 
  
 0.995
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).
 
  
 0.988
pqqF
Coenzyme PQQ biosynthesis protein PqqF; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the peptidase M16 family.
 
   
 0.891
APZ03868.1
Membrane-bound PQQ-dependent dehydrogenase, glucose/quinate/shikimate family; Quinoprotein glucose dehydrogenase; catalyzes the formation of D-glucono-1,5-lactone from D-glucose and ubiquinone; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.683
APZ05186.1
Peptidase; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.618
pqqA
Coenzyme PQQ precursor peptide PqqA; 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.
