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

Score
pepAAminopeptidase A/I; Presumably involved in the processing and regular turnover of intracellular proteins. Catalyzes the removal of unsubstituted N- terminal amino acids from various peptides. (502 aa)    
Predicted Functional Partners:
gshB
Glutathione synthetase.
   
 
 0.927
gshA
Glutamate--cysteine ligase; Belongs to the glutamate--cysteine ligase type 1 family. Type 1 subfamily.
     
  0.900
cysK
Cysteine synthase A; Belongs to the cysteine synthase/cystathionine beta- synthase family.
    
 0.815
valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.
  
   0.624
yceA
Hypothetical 40.0 kDa protein; Protein in htrB-dinI; Belongs to the UPF0176 family.
       0.568
argF
Ornithine carbamoyltransferase chain F; Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. OTCase family.
       0.513
lepB
Signal peptidase I; Belongs to the peptidase S26 family.
     
 0.484
flgG
Flagellar basal-body rod protein FlgG; Belongs to the flagella basal body rod proteins family.
    
   0.429
flgJ
Flagellar protein flgJ.
      
 0.422
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
    
  0.403
