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

pqqCCoenzyme PQQ 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
Coenzyme PQQ biosynthesis protein B; May be involved in the transport of PQQ or its precursor to the periplasm; Belongs to the PqqB family.
  
 0.998
pqqE
Coenzyme PQQ 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).
 
  
 0.991
pqqD
Coenzyme PQQ synthesis D; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway.
 
  
 0.988
ACA75304.1
PFAM: peptidase S9 prolyl oligopeptidase active site domain protein; KEGG: pen:PSEEN0393 prolyl oligopeptidase.
 
  
 0.906
ACA75298.1
TIGRFAM: coenzyme PQQ biosynthesis protein PqqF; PFAM: peptidase M16 domain protein; KEGG: pen:PSEEN0399 coenzyme PQQ synthesis protein F.
     
 0.838
ACA73188.1
KEGG: azo:azo3022 putative quinoprotein ethanol dehydrogenase; TIGRFAM: PQQ-dependent dehydrogenase, methanol/ethanol family; PFAM: Pyrrolo-quinoline quinone; cytochrome c class I.
 
  
 0.739
pqqA
Coenzyme PQQ biosynthesis protein A; 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.
