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

thrCThreonine synthase (thrC); Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine. (405 aa)    
Predicted Functional Partners:
thrB
Homoserine kinase (thrB); Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
  
 
 0.999
hom
Homoserine dehydrogenase (hom); Similar to SP:P19582 GB:M23217 PID:558494 PID:809663 GB:AL009126 percent identity: 40.32; identified by sequence similarity; putative; Belongs to the homoserine dehydrogenase family.
 
 
 0.996
leuD
3-isopropylmalate dehydratase (leuD); Enzyme with broad specificity that catalyzes reversible hydroxyacid isomerizations via dehydration/hydration reactions. Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate, a step involved in leucine biosynthesis. Catalyzes the isomerization between 2-methylmalate and 3-methylmalate, via the formation of 2-methylmaleate (citraconate), a step involved in isoleucine biosynthesis. Also displays malease activity, i.e. catalyzes the hydration of maleate to form (R)-malate.
  
  
 0.994
MJ_0571
Aspartate kinase (lysC); Similar to PID:928811 SP:P53553 percent identity: 40.95; identified by sequence similarity; putative; Belongs to the aspartokinase family.
  
 
 0.979
asd
Aspartate-semialdehyde dehydrogenase (asd); Catalyzes the NADPH-dependent formation of L-aspartate- semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl- 4-phosphate. To a lesser extent, is able to use NAD instead of NADP. Belongs to the aspartate-semialdehyde dehydrogenase family.
  
 
 0.944
ilvC
Ketol-acid reductoisomerase (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.
  
  
 0.902
pyrD
Dihydroorotase dehydrogenase (pyrD); Catalyzes the conversion of dihydroorotate to orotate with NAD(+) as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 1 subfamily.
  
 
 0.869
pdxS
Ethylene-inducible protein; Catalyzes the formation of pyridoxal 5'-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by the PdxT subunit. Can also use ribulose 5- phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively. Belongs to the PdxS/SNZ family.
  
  
 0.834
ilvE
Branched-chain amino acid aminotransferase (ilvE); Acts on leucine, isoleucine and valine; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
 
 0.797
ilvH
Acetolactate synthase small subunit (ilvN); Similar to GB:L03181 SP:P37252 PID:143092 PID:1770067 GB:AL009126 percent identity: 49.37; identified by sequence similarity; putative; Belongs to the acetolactate synthase small subunit family.
