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

serCPhosphoserine aminotransferase (phosphoserine transaminase); Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine. (373 aa)    
Predicted Functional Partners:
CBL56532.1
D-3-phosphoglycerate dehydrogenase / erythronate 4-phosphate dehydrogenase; Catalyzes the reversible oxidation of 3-phospho-D-glycerate to 3-phosphonooxypyruvate, the first step of the phosphorylated L- serine biosynthesis pathway. Also catalyzes the reversible oxidation of 2-hydroxyglutarate to 2-oxoglutarate; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
 
 0.987
serB/thrH
Phosphoserine phosphatase/homoserine phosphotransferase bifunctional protein; O-Phospho-L-serine + H2O <=> L-Serine + Orthophosphate and D-O-Phosphoserine + H2O <=> D-Serine + Orthophosphate.
  
 
 0.950
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.
   
 0.934
cys1
Cysteine synthase 1; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 
 0.913
cysK
Cysteine synthase (O-acetylserine sulfhydrylase); O3-acetyl-L-serine + H2S = L-cysteine + acetate. COFACTOR: Pyridoxal phosphate Belongs to the cysteine synthase/cystathionine beta-synthase family.
  
 
 0.913
cys2
Cysteine synthase 2; Formation of cysteine from O-acetyl-serine and hydrogen sulfide. O3-acetyl-L-serine + H2S = L-cysteine + acetate; Belongs to the cysteine synthase/cystathionine beta- synthase family.
  
 
 0.913
CBL57693.1
Hydroxyacid dehydrogenase; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
     
 0.905
serA
3-Phosphoglycerate + NAD+ <=> 3-Phosphonooxypyruvate + NADH + H+ glycine, serine, threonine metabolism.
  
 0.904
glyA
Glycine hydroxymethyltransferase precursor; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.

dtxR
Iron-dependent repressor.
