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

Saci_0763Thiamine pyrophosphate-requiring enzyme. (540 aa)    
Predicted Functional Partners:
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.
 
  
 0.755
ilvD
Dihydroxyacid dehydratase/phosphogluconate dehydratase; Belongs to the IlvD/Edd family.
 
  
 0.729
ilvB-2
Acetolactate synthase large subunit.
  
     0.725
Saci_1743
Thiamine pyrophosphate enzyme; Belongs to the TPP enzyme family.
  
     0.706
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 2 subfamily.
 
  
 0.578
hdh
Homoserine dehydrogenase.
 
  
 0.576
leu2
3-isopropylmalate dehydratase large subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.
 
  
 0.571
leuB
3-isopropylmalate dehydrogenase.
  
 
 0.561
Saci_0765
Conserved Archaeal protein.
       0.529
Saci_0940
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). Carries out the first step of the leucine biosynthesis pathway. Also displays a low citramalate synthase activity, using pyruvate as substrate, but is unable to use 2-oxoglutarate.
