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

Score
thrAAspartokinase I / homoserine dehydrogenase I (thrA); Similar to SP:P00561 GB:M10644 GB:V00360 GB:V00361 PID:147979 percent identity: 62.21; identified by sequence similarity; putative; In the C-terminal section; belongs to the homoserine dehydrogenase family. (815 aa)    
Predicted Functional Partners:
thrC
Threonine synthase (thrC); Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine.
 
 0.999
thrB
Homoserine kinase (thrB); Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
 
 0.999
asd
Aspartate-semialdehyde dehydrogenase (asd); Catalyzes the NADPH-dependent formation of L-aspartate- semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl- 4-phosphate; Belongs to the aspartate-semialdehyde dehydrogenase family.
  
 0.987
metXA
Homoserine acetyltransferase (met2); Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine. Utilizes a ping-pong kinetic mechanism in which the acetyl group of acetyl-CoA is initially transferred to the enzyme to form an acetyl- enzyme intermediate before subsequent transfer to homoserine to form the final product, O-acetylhomoserine.
 
 
 0.983
ilvH
Acetolactate synthase III small subunit (ilvH); Similar to GB:D10483 SP:P00894 GB:X01609 PID:216495 PID:40846 percent identity: 65.62; identified by sequence similarity; putative; Belongs to the acetolactate synthase small subunit family.
  
 
 0.982
usg
Usg-1 protein (usg1); Similar to SP:P08390 GB:X02743 PID:147125 PID:41717 GB:U00096 percent identity: 32.71; identified by sequence similarity; putative; Belongs to the aspartate-semialdehyde dehydrogenase family.
  
 0.981
metF
5,10 methylenetetrahydrofolate reductase (metF); Similar to GB:L19201 SP:P00394 GB:V01502 PID:305044 PID:42000 percent identity: 73.10; identified by sequence similarity; putative; Belongs to the methylenetetrahydrofolate reductase family.
  
 
 0.956
metB
Cystathionine gamma-synthase (metB); Catalyzes the formation of L-cystathionine from O-succinyl-L- homoserine (OSHS) and L-cysteine, via a gamma-replacement reaction. In the absence of thiol, catalyzes gamma-elimination to form 2- oxobutanoate, succinate and ammonia (By similarity).
  
 
 0.928
lysA
Diaminopimelate decarboxylase (lysA); Specifically catalyzes the decarboxylation of meso- diaminopimelate (meso-DAP) to L-lysine.
 
 
 0.928
ilvA
Threonine deaminase (ilvA); 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 (By similarity).
