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

fhsFormate--tetrahydrofolate ligase; ATP + formate + tetrahydrofolate = ADP + phosphate + 10-formyltetrahydrofolate; Belongs to the formate--tetrahydrofolate ligase family. (558 aa)    
Predicted Functional Partners:
folD
Methylenetetrahydrofolate dehydrogenase (Bifunctional protein); Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.994
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase (AICAR transformylase); 10-formyltetrahydrofolate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxamide = tetrahydrofolate + 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4- carboxamide and IMP + H2O = 5-formamido-1-(5-phospho-D-ribosyl)imidazole-4- carboxamide.
  
 0.981
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.
  
 0.970
purN
5-phosphoribosylglycinamide formyltransferase (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.
  
 0.962
metH
Methionine synthase (5-methyltetrahydrofolate:L-homocysteine S-methyltransferase); 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.
  
 
 0.962
gcvT1
Glycine cleavage system T protein, aminomethyltransferase; S-Aminomethyldihydrolipoylprotein + Tetrahydrofolate <=> Dihydrolipoylprotein + 5,10-Methylenetetrahydrofolate + NH3.
  
 0.944
folA
Dihydrofolate reductase; 5,6,7,8-tetrahydrofolate + NADP+ = 7,8-dihydrofolate + NADPH. tetrahydrofolate biosynthesis; tetrahydrofolate from 2-amino-4-hydroxy-6-hydroxymethyl-7,8-dihydropteridine diphosphate and 4-aminobenzoate: step 3/3.
  
 
 0.928
purL
Phosphoribosylformylglycinamidine synthase II (FGAM synthase II); Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is [...]
  
 
 0.863
purC
Phosphoribosylaminoimidazole-succinocarboxamide synthase; Catalyzes the seventh step of the de novo biosynthesis of purine nucleotides, the conversion of carboximideaminoimidazole ribonucleotide (CAIR) into succinoaminoimidazolecarboximide ribonucleotide (SAICAR). CAIR and aspartic acid react in the presence of ATP and magnesium to form SAICAR.
  
 
 0.809
gcvP
Glycine dehydrogenase [decarboxylating] (Glycine decarboxylase) (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.
