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

ggtGamma-glutamyltranspeptidase; Periplasmic enzyme; post-translationally processed into two subunits which are required for wild-type enzyme activity; cleaves the gammaglutamyl linkages of compounds such as glutathione and transfer the gammaglutamyl group to other amino acids and peptides; Derived by automated computational analysis using gene prediction method: Protein Homology. (580 aa)    
Predicted Functional Partners:
ybdK
Gamma-glutamyl ligase; ATP-dependent carboxylate-amine ligase which exhibits weak glutamate--cysteine ligase activity.

gshB
Catalyzes the second step in the glutathione biosynthesis pathway, where it synthesizes ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the prokaryotic GSH synthase family.
    
 0.920
pepA_3
Multifunctional aminopeptidase A; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides.
   
 
 0.919
gor
Catalyzes the reduction of 2 glutathione to glutathione disulfide; maintains high levels of reduced glutathione in the cytosol; involved in redox regulation and oxidative defense; Derived by automated computational analysis using gene prediction method: Protein Homology.
