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

pqqBCoenzyme PQQ synthesis protein B; 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
Coenzyme PQQ synthesis 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.
  
 0.997
pqqD
Coenzyme PQQ synthesis protein D; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway.
 
  
 0.991
pqqE
Coenzyme PQQ synthesis 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).
 
  
 0.986
AAO54051.1
Conserved protein of unknown function; See PMID:20190049 for expression data.
 
  
 0.907
pqqF
Coenzyme PQQ synthesis 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).
     
 0.704
pqqA
Coenzyme PQQ synthesis 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 (By similarity); Belongs to the PqqA family.

gcd-1
Glucose dehydrogenase; Similar to SP:Q9XD78, and SP:P15877; identified by sequence similarity; putative.
 
  
 0.560
AAO58057.1
Conserved domain protein; Similar to GP:15082090; identified by sequence similarity; putative; see PMID:20190049 for expression data; similar to GP:15082090, identified by sequence similarity, putative.

gcd
Glucose dehydrogenase; See PMID:20190049 for expression data; similar to SP:P15877; identified by sequence similarity; putative.
 
  
 0.534
pvdQ
Penicillin amidase family protein; Catalyzes the deacylation of acyl-homoserine lactone (AHL or acyl-HSL), releasing homoserine lactone (HSL) and the corresponding fatty acid. Possesses a specificity for the degradation of long-chain acyl-HSLs (side chains of 11 to 14 carbons in length) (By similarity).
