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

leuB3-isopropylmalate dehydrogenase; Catalyzes the oxidation of 3-carboxy-2-hydroxy-4- methylpentanoate (3-isopropylmalate) to 3-carboxy-4-methyl-2- oxopentanoate. The product decarboxylates to 4-methyl-2 oxopentanoate. (360 aa)    
Predicted Functional Partners:
leuC
3-isopropylmalate dehydratase, large subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.
 0.999
SCY60836.1
3-isopropylmalate/(R)-2-methylmalate dehydratase small subunit; Belongs to the LeuD family.
 
 
 0.994
SCY87769.1
Acetolactate synthase, small subunit.
 
 0.954
SCY87757.1
Acetolactate synthase, large subunit.
 0.939
SCY14319.1
Acetolactate synthase, large subunit.
 0.935
leuA
2-isopropylmalate synthase; 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); Belongs to the alpha-IPM synthase/homocitrate synthase family. LeuA type 1 subfamily.
 0.928
SCY90856.1
Homocitrate synthase NifV; Belongs to the alpha-IPM synthase/homocitrate synthase family.
 0.925
ilvC
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.
 
  
 0.922
ilvD
Dihydroxyacid dehydratase; Belongs to the IlvD/Edd family.
 
  
 0.918
SCY72626.1
Dihydroxyacid dehydratase/phosphogluconate dehydratase; Belongs to the IlvD/Edd family.
 
  
 0.885
