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

DC74_1873Pyridoxal-5'-phosphate-dependent protein subunit beta. (402 aa)    
Predicted Functional Partners:
thrB_3
Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily.
 
 
 0.984
ilvA
Threonine dehydratase; 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.
  
 
 0.935
serC
Phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
   
 0.935
DC74_5137
Threonine dehydratase.
  
 
 0.935
DC74_7789
Threonine dehydratase.
  
 
 0.935
DC74_1832
L-threonine aldolase.
  
 0.926
tdh
L-threonine 3-dehydrogenase; Catalyzes the NAD(+)-dependent oxidation of L-threonine to 2- amino-3-ketobutyrate; Belongs to the zinc-containing alcohol dehydrogenase family.
   
 
  0.900
DC74_1872
IlvB; Belongs to the TPP enzyme family.
 
  
 0.836
DC74_5466
Homoserine dehydrogenase.
  
 
 0.832
DC74_1874
Hypothetical protein.
