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

ptrAProtease 3 precursor; Belongs to the peptidase M16 family. (422 aa)    
Predicted Functional Partners:
hndC_1
NADP-reducing hydrogenase subunit HndC.
  
 
 0.997
sfrB_1
NADPH-Fe(3+) oxidoreductase subunit beta.
  
 
 0.974
nqo4
NADH-quinone oxidoreductase subunit 4; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be a menaquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; Belongs to the complex I 49 kDa subunit family.
   
 
 0.965
hndC_3
NADP-reducing hydrogenase subunit HndC.
  
 
 0.962
ndhJ
NAD(P)H-quinone oxidoreductase subunit J; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. Belongs to the complex I 30 kDa subunit family.
