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.

Ping_1277KEGG: vvy:VV0652 threonine synthase; TIGRFAM: threonine synthase; PFAM: Pyridoxal-5'-phosphate-dependent enzyme, beta subunit. (425 aa)    
Predicted Functional Partners:
Ping_1275
Aspartate kinase; KEGG: vfi:VF2118 bifunctional aspartokinase I/homeserine dehydrogenase I; TIGRFAM: aspartate kinase; PFAM: aspartate/glutamate/uridylate kinase; homoserine dehydrogenase; amino acid-binding ACT domain protein; homoserine dehydrogenase, NAD-binding; In the C-terminal section; belongs to the homoserine dehydrogenase family.
 
 
 0.999
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
Ping_0508
Phosphoserine aminotransferase apoenzyme; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine.
  
 0.942
ilvA
L-threonine ammonia-lyase; 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.
  
 
 0.941
serC
Phosphoserine aminotransferase apoenzyme; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
   
 0.933
Ping_2292
L-threonine aldolase; PFAM: aromatic amino acid beta-eliminating lyase/threonine aldolase; KEGG: ppr:PBPRB0795 putative threonine aldolase.
    
 0.924
tdh
L-threonine 3-dehydrogenase; Catalyzes the NAD(+)-dependent oxidation of L-threonine to 2- amino-3-ketobutyrate; Belongs to the zinc-containing alcohol dehydrogenase family.
   
 
 0.908
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).
    
  0.902
leuD
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.
 
  
 0.845
Ping_0853
Ketol-acid reductoisomerase; 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.
