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

PAE2878Threonine synthase; Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine. (348 aa)    
Predicted Functional Partners:
thrB
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
  
 
 0.999
PAE2868
Homoserine dehydrogenase; Amino acid biosynthesis; Aspartate family.
 
 
 0.994
PAE2877
Aspartate kinase; Amino acid biosynthesis; Aspartate family.
  
 
 0.985
PAE2316
Threonine dehydratase (ilvA); Amino acid biosynthesis; Pyruvate family.
 
 
0.982
PAE2876
Aspartate-semialdehyde dehydrogenase (asd); Amino acid biosynthesis; Aspartate family.
  
 
 0.952
leuD
3-isopropylmalate dehydratase small subunit (leuD); Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 2 subfamily.
  
  
 0.909
ilvC
Acetohydroxy acid isomeroreductase (ilvC); Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate.
  
  
 0.865
ilvE
Branched-chain amino acid aminotransferase (ilvE); Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
 
 
 0.766
PAE3320
D-3-phosphoglycerate dehydrogenase (serA); Amino acid biosynthesis; Serine family; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
  
  
 0.756
PAE1995
3-isopropylmalate dehydrogenase (leuB); Amino acid biosynthesis; Pyruvate family.
  
 
 0.721
