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 (leuB); 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 (By similarity); Belongs to the isocitrate and isopropylmalate dehydrogenases family. (326 aa)    
Predicted Functional Partners:
leuD1
3-isopropylmalate dehydratase, small subunit (leuD-1); Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 2 subfamily.
 
 0.999
leuC1
Aconitase (acn); Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.
 0.998
leuC2
3-isopropylmalate dehydratase, large subunit (leuC); Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.
 0.998
ilvH
Acetolactate synthase, small subunit (ilvN); Similar to GB:L77117 SP:Q57625 PID:1590918 percent identity: 60.38; identified by sequence similarity; putative; Belongs to the acetolactate synthase small subunit family.
  
 0.995
leuD2
3-isopropylmalate dehydratase, small subunit (leuD-2); Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 2 subfamily.
 
 0.994
leuA
2-isopropylmalate synthase (leuA-2); 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).
 
 0.983
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 or NADH to yield (R)-2,3-dihydroxy-isovalerate. It is able to use both NADPH and NADH, but has a preference for NADH.
