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.

Pden_2170TIGRFAM: acetolactate synthase, small subunit; PFAM: amino acid-binding ACT domain protein; KEGG: rsp:RSP_2636 acetolactate synthase small subunit. (186 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.

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.

Pden_4062
TIGRFAM: 2-isopropylmalate synthase/homocitrate synthase family protein; PFAM: pyruvate carboxyltransferase; LeuA allosteric (dimerisation) domain; KEGG: jan:Jann_1959 2-isopropylmalate synthase/homocitrate synthase; Belongs to the alpha-IPM synthase/homocitrate synthase family.

Pden_0285
PFAM: Pyridoxal-5'-phosphate-dependent enzyme, beta subunit; KEGG: ret:RHE_PF00182 probable threonine dehydratase protein.
 
 0.948
ilvA
L-threonine ammonia-lyase; 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.

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 1 subfamily.
 
 
 0.945
bhcB
Pyridoxal-5'-phosphate-dependent enzyme, beta subunit; Catalyzes the dehydration of (2R,3S)-beta-hydroxyaspartate ((3S)-3-hydroxy-D-aspartate) into iminosuccinate. Is essential for the growth of P.denitrificans in the presence of glycolate and glyoxylate since it functions in glyoxylate assimilation via the beta- hydroxyaspartate cycle (BHAC).
  
 0.941
leuC
3-isopropylmalate dehydratase, large subunit; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.

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.
