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.

purUFormyltetrahydrofolate deformylase; Catalyzes the hydrolysis of 10-formyltetrahydrofolate (formyl-FH4) to formate and tetrahydrofolate (FH4). (284 aa)    
Predicted Functional Partners:
folD
Methylenetetrahydrofolate dehydrogenase (NADP(+)); Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.950
glyA
Glycine 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.
  
 
 0.941
gcvT
Glycine cleavage system T protein; The glycine cleavage system catalyzes the degradation of glycine.
  
 
 0.923
Slit_0060
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.
    
 0.921
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.

purH
SMART: AICARFT/IMPCHase bienzyme formylation region; MGS domain protein; TIGRFAM: phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; KEGG: nmu:Nmul_A0133 bifunctional phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: AICARFT/IMPCHase bienzyme formylation region; MGS domain protein.
     
 0.916
Slit_2522
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
     
 0.903
mqo
TIGRFAM: malate/quinone oxidoreductase; KEGG: hch:HCH_04006 malate:quinone oxidoreductase; PFAM: Malate:quinone-oxidoreductase.
    
  0.816
ppc
Phosphoenolpyruvate carboxylase; Forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle; Belongs to the PEPCase type 1 family.
     
 0.803
Slit_0450
Malate dehydrogenase (oxaloacetate-decarboxylating) (NADP(+))., Phosphate acetyltransferase; KEGG: azo:azo3211 malic enzyme; PFAM: malic protein NAD-binding; malic protein domain protein; phosphate acetyl/butaryl transferase.
