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

ilvHSimilar to Mycobacterium tuberculosis acetolactate synthase small subunit IlvH or IlvN or Rv3002c or MT3082 or MTV012.16c SW:ILVH_MYCTU (O53249) (168 aa) fasta scores: E(): 1.3e-28, 54.77% id in 157 aa, and to Corynebacterium glutamicum (Brevibacterium flavum) acetohydroxy acid synthase, small subunit IlvN or LivS TR:Q57091 (EMBL:L09232) (172 aa) fasta scores: E(): 5.4e-47, 81.06% id in 169 aa. (174 aa)    
Predicted Functional Partners:
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.

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.

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.

DIP1952
Similar to Escherichia coli pyruvate dehydrogenase [cytochrome] PoxB SW:POXB_ECOLI (P07003) (572 aa) fasta scores: E(): 1.2e-100, 45.89% id in 573 aa, and to Streptomyces coelicolor pyruvate dehydrogenase SC1A9.19 TR:Q9ZBT3 (EMBL:AL034446) (580 aa) fasta scores: E(): 1.4e-132, 56.62% id in 581 aa; Belongs to the TPP enzyme family.
 
 0.988
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.
  
 
 0.985
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.
  
 
 0.971
DIP0990
Putative decarboxylase (internal pH control related); Similar to Bacillus subtilis alpha-acetolactate decarboxylase AlsD SW:ALDC_BACSU (Q04777) (255 aa) fasta scores: E(): 2.1e-38, 44.78% id in 230 aa.
     
 0.909
ilvD
Similar 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.

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.
