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

ilvEBranched-chain amino acid aminotransferase (ilvE); Acts on leucine, isoleucine and valine; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family. (288 aa)    
Predicted Functional Partners:
ilvD
Dihydroxy-acid dehydratase (ilvD); Similar to GB:M90761 SP:Q02139 PID:149431 percent identity: 44.53; identified by sequence similarity; putative; Belongs to the IlvD/Edd family.
  
 0.999
leuA
2-isopropylmalate synthase (leuA); Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3- hydroxy-4-methylpentanoate (2-isopropylmalate).
 
 0.990
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.

ilvB
Acetolactate synthase large subunit (ilvB); Similar to GB:L03181 SP:P37251 PID:143091 percent identity: 50.18; identified by sequence similarity; putative; Belongs to the TPP enzyme family.
  
 
 0.962
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.
  
 
 0.945
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.
  
 
 0.919
aksA
2-isopropylmalate synthase (leuA); Catalyzes the condensation of alpha-ketoglutarate and acetyl- CoA to form trans-homoaconitate. Can also catalyze the condensation of alpha-ketoadipate with acetyl-CoA to form (R)-homo(2)citrate, and the condensation of alpha-ketopimelate with acetyl-CoA to form (R)- homo(3)citrate; Belongs to the alpha-IPM synthase/homocitrate synthase family.

MJ_0663
Acetolactate synthase large subunit (ilvB); Similar to GB:L10328 SP:P08142 GB:J01633 GB:X02541 PID:146455 percent identity: 30.21; identified by sequence similarity; putative; Belongs to the TPP enzyme family.

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.

trpG
Anthranilate synthase component II (trpG); Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high [...]
