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

AFY48548.1Threonine synthase; Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine. (363 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.
 
 
 0.984
ilvA
Threonine ammonia-lyase, biosynthetic, long form; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.

AFY49271.1
Phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine.
   
 0.935
AFY49183.1
Threonine synthase; PFAM: Pyridoxal-phosphate dependent enzyme; TIGRFAM: threonine synthase.
  
  
 
0.919
pdxA
4-hydroxythreonine-4-phosphate dehydrogenase; Catalyzes the NAD(P)-dependent oxidation of 4-(phosphooxy)-L- threonine (HTP) into 2-amino-3-oxo-4-(phosphooxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP).
    
  0.903
AFY46903.1
PFAM: Homoserine dehydrogenase; Homoserine dehydrogenase, NAD binding domain; ACT domain.
 
 
 0.868
AFY48795.1
Aspartate kinase; PFAM: ACT domain; Amino acid kinase family; TIGRFAM: aspartate kinase, monofunctional class; aspartate kinase.
  
 
 0.795
AFY47857.1
3-isopropylmalate dehydratase, small subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 1 subfamily.
  
  
 0.775
AFY49982.1
PFAM: Conserved region in glutamate synthase; GXGXG motif; Glutamate synthase central domain; Glutamine amidotransferases class-II.
  
  
 0.663
AFY49727.1
PFAM: D-isomer specific 2-hydroxyacid dehydrogenase, NAD binding domain; ACT domain; D-isomer specific 2-hydroxyacid dehydrogenase, catalytic domain; TIGRFAM: D-3-phosphoglycerate dehydrogenase.
