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

ilvYTranscriptional activator of ilvC; This protein activates the transcription of the ilvC gene in the presence of acetolactate or acetohydroxybutyrate. IlvY is also a negative regulator of its own expression; Belongs to the LysR transcriptional regulatory family. (297 aa)    
Predicted Functional Partners:
ilvC
Ketol-acid reductoisomerase, NAD(P)-binding; 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. Also able to use 2-ketopantoate, 2-ketoisovalerate, 2-ketovalerate, 2-ketobutyrate [...]

tdcA
Tdc operon transcriptional activator; Transcriptional activator for the tdcABCDE operon. Belongs to the LysR transcriptional regulatory family.
  
     0.631
ilvA
L-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.
   
  
 0.573
cysB
N-acetylserine-responsive cysteine regulon transcriptional activator; This protein is a positive regulator of gene expression for the cysteine regulon, a system of 10 or more loci involved in the biosynthesis of L-cysteine from inorganic sulfate. The inducer for CysB is N-acetylserine. CysB inhibits its own transcription.
  
   
0.485
lrp
Leucine-responsive global transcriptional regulator; Mediates a global response to leucine. Exogenous leucine affects the expression of a number of different operons; lrp mediates this effect for at least some of these operons. For example it is regulator of the branched-chain amino acid transport genes.
      
 0.475
modF
Molybdate ABC transporter ATPase; Probably not involved in the transport of molybdenum into the cell; Belongs to the ABC transporter superfamily.
  
     0.450
cynR
Transcriptional activator of cyn operon; Positively regulates the cynTSX operon, and negatively regulates its own transcription. Binds specifically to the cynR-cynTSX intergenic region.
  
   
0.426
rhaS
Transcriptional activator of rhaBAD and rhaT; Activates expression of the rhaBAD and rhaT operons.
  
  
 0.418
metR
Methionine biosynthesis regulon transcriptional regulator; Control of the last step in methionine biosynthesis; MetR is a positive activator of the metA, metE and metH genes. MetR is also a negative regulator of its own expression. Binds homocysteine as an inducer; Belongs to the LysR transcriptional regulatory family.
