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

thrA/homL-Homoserine + NAD+ <=> L-Aspartate 4-semialdehyde + NADH + H+ and L-Homoserine + NADP+ <=> L-Aspartate 4-semialdehyde + NADPH + H+. (441 aa)    
Predicted Functional Partners:
asd
Aspartate-semialdehyde dehydrogenase (Semialdehyde dehydrogenase); 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.
 
 0.990
thrC
Threonine synthase (O-phospho-L-homoserine phosphate-lyase (adding water;L-threonine-forming)); O-Phospho-L-homoserine + H2O <=> L-Threonine + Orthophosphate / O-Phospho-4-hydroxy-L-threonine + H2O <=> 4-Hydroxy-L-threonine + Orthophosphate.
 
 
 0.981
serB/thrH
Phosphoserine phosphatase/homoserine phosphotransferase bifunctional protein; O-Phospho-L-serine + H2O <=> L-Serine + Orthophosphate and D-O-Phosphoserine + H2O <=> D-Serine + Orthophosphate.
  
 
 0.981
metH
Methionine synthase (5-methyltetrahydrofolate:L-homocysteine S-methyltransferase); Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
  
 
 0.961
ask
Aspartokinase (Aspartate kinase); ATP + L-Aspartate <=> ADP + 4-Phospho-L-aspartate; Belongs to the aspartokinase family.
 
 0.959
dapA
Dihydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
 
 
 0.959
pf3022
Homoserine O-acetyltransferase; Transfers a succinyl group from succinyl-CoA to L-homoserine, forming succinyl-L-homoserine.
 
 0.952
lysA
Diaminopimelate decarboxylase (DAP decarboxylase); Specifically catalyzes the decarboxylation of meso- diaminopimelate (meso-DAP) to L-lysine.
 
  
 0.921
metB
Cystathionine gamma-synthase (O-succinylhomoserine (thiol)-lyase).
  
 
 0.898
ilvE
Catalyzes the first reaction in the catabolism of the branched chain amino acids leucine, isoleucine, and valine. pyridoxal-phosphate dependent enzymes.
 
 
 0.888
