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

glyASerine hydroxymethyltransferase; 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. (425 aa)    
Predicted Functional Partners:
gcvP
Glycine dehydrogenase, glycine cleavage system P protein; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.
 
 
 0.998
gcvT
Aminomethyltransferase, glycine cleavage system T protein; The glycine cleavage system catalyzes the degradation of glycine.
 
 0.996
purH
Bifunctional purine biosynthesis protein PurH; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 0.988
folD
Bifunctional 5,10 methylene-tetrahydrofolate dehydrogenase/cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
  
 0.981
NIDE1059
Putative Aminomethyltransferase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the GcvT family.
 
 0.981
fhs
Formate-tetrahydrofolate ligase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the formate--tetrahydrofolate ligase family.
  
 0.980
gcvH
Glycine cleavage system, H protein; The glycine cleavage system catalyzes the degradation of glycine. The H protein shuttles the methylamine group of glycine from the P protein to the T protein.
 
 
 0.976
purN
Phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
  
 0.968
metF
5,10-methylenetetrahydrofolate reductase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the methylenetetrahydrofolate reductase family.
  
 
 0.945
metH
Methionine synthase; 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.
