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

pqqDCoenzyme PQQ synthesis protein D; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway. (94 aa)    
Predicted Functional Partners:
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.
 
  
 0.995
pqqB
Pyrroloquinoline quinone biosynthesis protein PqqB; May be involved in the transport of PQQ or its precursor to the periplasm, in association with PQQ biosynthesis, but is not absolutely required for this synthesis; Belongs to the PqqB family.
 
  
 0.992
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).
 
  
 0.990
AQZ81845.1
Peptidase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the metallo-dependent hydrolases superfamily. Peptidase M19 family.
       0.845
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 (By similarity); Belongs to the PqqA family.
     
 0.738
moaA
GTP 3',8-cyclase MoaA; Catalyzes the cyclization of GTP to (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate.
      
 0.526
AQZ82053.1
Membrane-bound PQQ-dependent dehydrogenase, glucose/quinate/shikimate family; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.486
