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

Score
ilvDSimilar to Streptomyces coelicolor dihydroxy-acid dehydratase IlvD or SCE7.12c SW:ILVD_STRCO (O69198) (617 aa) fasta scores: E(): 1.7e-161, 67.9% id in 617 aa, and to Escherichia coli dihydroxy-acid dehydratase IlvD or B3771 SW:ILVD_ECOLI (P05791) (616 aa) fasta scores: E(): 1.4e-155, 67.37% id in 613 aa; Belongs to the IlvD/Edd family. (613 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.

ilvE
Similar to Mycobacterium tuberculosis probable branched-chain amino acid aminotransferase IlvE or Rv2210c or MT2266 or MTCY190.21c SW:ILVE_MYCTU (Q10399) (368 aa) fasta scores: E(): 4.3e-93, 62.53% id in 363 aa, and to Bacillus subtilis putative branched-chain amino acid aminotransferase YwaA or Ipa-0R SW:ILVE_BACSU (P39576) (362 aa) fasta scores: E(): 1.1e-60, 44.62% id in 363 aa.
  
 0.995
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 2 subfamily.
  
 
 0.988
ilvB
Similar to Corynebacterium glutamicum acetolactate synthase large subunit IlvB SW:ILVB_CORGL (P42463) (626 aa) fasta scores: E(): 4.3e-181, 75.32% id in 620 aa, and to Mycobacterium tuberculosis acetolactate synthase IlvB or Rv3003c or MT3083 or MTV012.17c SW:ILVB_MYCTU (O53250) (618 aa) fasta scores: E(): 1.6e-152, 64.94% id in 599 aa.
  
 0.986
leuB
3-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. Belongs to the isocitrate and isopropylmalate dehydrogenases family. LeuB type 2 subfamily.
 
  
 0.928
panB
3-methyl-2-oxobutanoate hydroxymethyltransferase; Catalyzes the reversible reaction in which hydroxymethyl group from 5,10-methylenetetrahydrofolate is transferred onto alpha- ketoisovalerate to form ketopantoate; Belongs to the PanB family.

DIP2136
Putative aminotransferase; Similar to Mycobacterium tuberculosis probable aspartate aminotransferase AspC or Rv0337c or MT0351 or MTCY279.04c SW:AAT_MYCTU (O33267) (429 aa) fasta scores: E(): 2.4e-120, 71.32% id in 415 aa, and to Escherichia coli probable aminotransferase YfbQ or B2290 SW:YFBQ_ECOLI (P77727) (405 aa) fasta scores: E(): 1.8e-101, 61.59% id in 401 aa, and to Methylobacillus flagellatum aspartate aminotransferase Aat TR:Q9RAN0 (EMBL:L78665) (429 aa) fasta scores: E(): 1.7e-87, 55.08% id in 403 aa.
   
 
 0.912
ilvA
Threonine dehydratase biosynthetic; 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.
