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

leuDLeuD protein; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate. Belongs to the LeuD family. LeuD type 1 subfamily. (212 aa)    
Predicted Functional Partners:
leuC
LeuC protein; Catalyzes the isomerization between 2-isopropylmalate and 3- isopropylmalate, via the formation of 2-isopropylmaleate.
 0.999
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.
 
 
 0.999
leuA1
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.
 
 
 0.991
leuA2
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.
 
 
 0.989
ilvC
IlvC protein; 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.

yeaU
Tartrate dehydrogenase catalyzes the reduction of tartrate to oxaloglycolate. Similar to sprot|TTUC_ECOLI (75%) and to sprot|TTUC_PSEPU (76%). Pfam (PF00180): Isocitrate and isopropylmalate dehydrogenases; High confidence in function and specificity.
 
 
 0.951
ilvD
Dihydroxy-acid dehydratase catalyzes the fourth step in the biosynthesis of isoleucine and valine, the dehydratation of 2,3-dihydroxy-isovaleic acid into alpha-ketoisovaleric acid. Similar to sprot|ILVD_PSEAE (74%) and sprot|ILVD_ECOL6 (72%). TIGRfam (TIGR00110): Dihydroxy-acid dehydratase Pfam (PF00920): Dihydroxy-acid and 6-phosphogluconate dehydratase; High confidence in function and specificity; Belongs to the IlvD/Edd family.

maeB1
Probable malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+) (EC 1.1.1.40) (NADP-ME). Homology to dme of S. meliloti of 60% (sprot|MAO1_RHIME). Required for symbiotic nitrogen fixation. Plays a key role in the conversion of malate to acetyl-CoA for efficient tricarboxylic acid cycle function in nitrogen-fixating bacteria. Tigrfam: pta: phosphotransacetylase Pfam: Malic enzyme; Phosphate acetyl/butaryltransferase no signal peptide no TMHs; High confidence in function and specificity.
