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

ilvDRv0189c, (MTCI28.28c), len: 575 aa. Probable ilvD,dihydroxy-acid dehydratase, similar to many e.g. ILVD_LACLA|Q02139 dihydroxy-acid dehydratase (dad) from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (570 aa), FASTA scores: opt: 1605, E(): 0, (46.0% identity in 561 aa overlap). Also similar to ML2608|MLCL622.06c|O06069|ILVD_MYCLE dihydroxy-acid dehydratase from Mycobacterium leprae (564 aa). Contains PS00886 Dihydroxy-acid and 6-phosphogluconate dehydratases signature 1. Belongs to the ILVD / EDD family. Cofactor: binds 1 4FE-4S cluster (potential). (575 aa)    
Predicted Functional Partners:
ilvC
Ketol-acid reductoisomerase (NADP(+)); 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. It is also able to use 3-hydroxypyruvate (HP).
 
 
 0.998
ilvE
Branched-chain amino acid transaminase IlvE; Catalyzes the reversible transfers of an amino group from glutamate to the alpha-ketoacid of the respective amino acid in the final step in the biosynthesis of branchedchain amino acids. The amino acids can be ranked in the following order with respect to their efficiency as amino donor: Leu > Ile > Val. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
 
 0.994
leuA
2-isopropylmalate synthase LeuA (alpha-isopropylmalate synthase) (alpha-IPM synthetase) (IPMS); 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).
  
 
 0.988
leuC
3-isopropylmalate dehydratase large subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.
 
  
 0.967
leuB
Probable 3-isopropylmalate dehydrogenase LeuB (beta-IPM dehydrogenase) (IMDH) (3-IPM-DH); 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; Belongs to the isocitrate and isopropylmalate dehydrogenases family. LeuB type 2 subfamily.
 
  
 0.967
ilvB1
Acetolactate synthase (large subunit) IlvB1 (acetohydroxy-acid synthase); Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine. Also involved in condensing pyruvate and 2-ketobutyrate to form 2-aceto-2- hydroxybutyrate.
  
 0.967
ilvN
Probable acetolactate synthase (small subunit) IlvN (acetohydroxy-acid synthase) (AHAS) (ALS); Catalyzes the conversion of 2 pyruvate molecules into acetolactate in the first common step of the biosynthetic pathway of the branched-amino acids such as leucine, isoleucine, and valine. Belongs to the acetolactate synthase small subunit family.
 
 
 0.960
ilvA
Probable threonine dehydratase IlvA; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA (By similarity).

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 1 subfamily.
