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

 0.984
alr4552
Cysteine synthase; ORF_ID:alr4552; Belongs to the cysteine synthase/cystathionine beta- synthase family.
 
 0.984
all1169
Cysteine synthase; ORF_ID:all1169.
 
 0.973
alr4416
Cystathionine beta-synthase; ORF_ID:alr4416.
 
 0.964
cysS
cysteinyl-tRNA synthetase; ORF_ID:all1092; cysS gene product; Belongs to the class-I aminoacyl-tRNA synthetase family.
 
  
 0.939
alr1404
Serine acetyltransferase; ORF_ID:alr1404.
  
  
 
0.902
alr4806
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
     
 0.830
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
     
 0.829
thrA
Homoserine dehydrogenase; ORF_ID:all4120.
     
 0.815
trpA
Tryptophan synthase alpha chain; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
     
 0.804
