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

ilvEBranched-chain amino acid aminotransferase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family. (306 aa)    
Predicted Functional Partners:
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.
 
 0.996
ilvD
Dihydroxy-acid dehydratase; Identified by similarity to SP:P51785; match to protein family HMM PF00920; match to protein family HMM TIGR00110; Belongs to the IlvD/Edd family.
  
 0.983
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.
     
 0.916
nifV
Homocitrate synthase; Identified by similarity to SP:P05342; match to protein family HMM PF00682; Belongs to the alpha-IPM synthase/homocitrate synthase family.
 
 
 0.910
ilvA
Threonine ammonia-lyase, 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.
  
 
 0.904
gshA
Glutamate--cysteine ligase; Identified by similarity to SP:P06980; match to protein family HMM PF04262; match to protein family HMM TIGR01434; Belongs to the glutamate--cysteine ligase type 1 family. Type 1 subfamily.
     
  0.900
hom
Homoserine dehydrogenase; Identified by similarity to SP:P29365; match to protein family HMM PF00742; match to protein family HMM PF01842; match to protein family HMM PF03447.
  
 
 0.858
glnE
Glutamate-ammonia-ligase adenylyltransferase; Involved in the regulation of glutamine synthetase GlnA, a key enzyme in the process to assimilate ammonia. When cellular nitrogen levels are high, the C-terminal adenylyl transferase (AT) inactivates GlnA by covalent transfer of an adenylyl group from ATP to specific tyrosine residue of GlnA, thus reducing its activity. Conversely, when nitrogen levels are low, the N-terminal adenylyl removase (AR) activates GlnA by removing the adenylyl group by phosphorolysis, increasing its activity. The regulatory region of GlnE binds the signal transd [...]

edd
6-phosphogluconate dehydratase; Catalyzes the dehydration of 6-phospho-D-gluconate to 2- dehydro-3-deoxy-6-phospho-D-gluconate; Belongs to the IlvD/Edd family.
  
 
 0.583
pheA
Chorismate mutase/prephenate dehydratase; Identified by similarity to SP:P27603; match to protein family HMM PF00800; match to protein family HMM PF01817; match to protein family HMM PF01842; match to protein family HMM TIGR01807.
