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

pqqDPyrroloquinoline quinone biosynthesis protein D; Functions as a PqqA binding protein and presents PqqA to PqqE, in the pyrroloquinoline quinone (PQQ) biosynthetic pathway. (95 aa)    
Predicted Functional Partners:
pqqC
Pyrroloquinoline-quinone synthase; 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.
 
  
 0.994
pqqE
Pyrroloquinoline quinone 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).
 
  
 0.986
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.
 
  
 0.985
SHM87295.1
Dipeptidyl aminopeptidase/acylaminoacyl peptidase.
 
  
 0.920
SHM87268.1
Insulinase (Peptidase family M16).
 
   
 0.911
SHM87425.1
PQQ-dependent dehydrogenase, methanol/ethanol family.
 
  
 0.722
SHM87544.1
PQQ-dependent catabolism-associated beta-propeller protein.
  
     0.486
SHM87518.1
ABC transporter, substrate binding protein, PQQ-dependent alcohol dehydrogenase system.
  
     0.464
SHL31880.1
Pilin (type 1 fimbria component protein).
  
     0.449
hslU
ATP-dependent HslUV protease ATP-binding subunit HslU; ATPase subunit of a proteasome-like degradation complex; this subunit has chaperone activity. The binding of ATP and its subsequent hydrolysis by HslU are essential for unfolding of protein substrates subsequently hydrolyzed by HslV. HslU recognizes the N-terminal part of its protein substrates and unfolds these before they are guided to HslV for hydrolysis.
