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

thrBHomoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily. (309 aa)    
Predicted Functional Partners:
thrA
Fused aspartokinase I and homoserinedehydrogenase I; In the N-terminal section; belongs to the aspartokinase family.
 
 0.999
thrC
Threonine synthase; Catalyzes the gamma-elimination of phosphate from L- phosphohomoserine and the beta-addition of water to produce L- threonine.
 
 0.999
metL
Bifunctional aspartokinase/homoserinedehydrogenase II; In the C-terminal section; belongs to the homoserine dehydrogenase family.
 
 0.999
lysC
Aspartokinase III; Belongs to the aspartokinase family.
 
 
 0.931
metH
homocysteine-N5- methyltetrahydrofolatetransmethylase,B12-dependent; 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.
    
 0.900
metE
5-methyltetrahydropteroyltriglutamate- homocysteine S-methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.
  
 
 0.851
ilvE
Branched-chain amino-acid aminotransferase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
 
 0.848
sdaB
L-serine deaminase II; Belongs to the iron-sulfur dependent L-serine dehydratase family.
  
 
 0.839
sdaA
L-serine deaminase I; Belongs to the iron-sulfur dependent L-serine dehydratase family.
  
 
 0.839
CDG11481.1
Putative cystathionine beta-lyase.
  
 
 0.835
