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

pqqBPyrroloquinoline quinone biosynthesis 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
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.
  
 0.997
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
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
AMB83891.1
Pyrroloquinoline quinone biosynthesis protein PqqF; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the peptidase M16 family.
     
 0.559
pqqA
Pyrroloquinoline quinone biosynthesis protein 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.
       0.547
AMB85059.1
Carbon-phosphorus lyase; Catalyzes the breakage of the C-P bond in alpha-D-ribose 1- methylphosphonate 5-phosphate (PRPn) forming alpha-D-ribose. Belongs to the PhnJ family.
  
 
 0.540
lipA
Lipoyl synthase; Catalyzes the radical-mediated insertion of two sulfur atoms into the C-6 and C-8 positions of the octanoyl moiety bound to the lipoyl domains of lipoate-dependent enzymes, thereby converting the octanoylated domains into lipoylated derivatives.
    
 0.500
AMB85057.1
Phosphonate ABC transporter ATP-binding protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.454
AMB85056.1
alpha-D-ribose 1-methylphosphonate 5-triphosphate diphosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.452
