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

folADihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. (170 aa)    
Predicted Functional Partners:
thyA
Thymidylate synthase; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.
 
 
 0.996
glyA
Serine 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.

fmt
methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
  
 
 0.917
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
Bifunctional purine biosynthesis protein PurH; Identified by match to protein family HMM PF01808; match to protein family HMM PF02142; match to protein family HMM TIGR00355.
    
 0.913
fhs-1
Formate--tetrahydrofolate ligase; Identified by match to protein family HMM PF01268; Belongs to the formate--tetrahydrofolate ligase family.
  
 
 0.911
fhs-2
Formate--tetrahydrofolate ligase; Identified by match to protein family HMM PF01268; Belongs to the formate--tetrahydrofolate ligase family.

SGO_1913
Dihydrofolate synthetase; Identified by match to protein family HMM PF02875; match to protein family HMM PF08245; match to protein family HMM TIGR01499; Belongs to the folylpolyglutamate synthase family.
     
 0.911
SGO_2039
Dihydrofolate synthase; Identified by match to protein family HMM PF02875; match to protein family HMM PF08245; match to protein family HMM TIGR01499; Belongs to the folylpolyglutamate synthase family.
     
 0.911
ftcD
Glutamate formiminotransferase; Identified by match to protein family HMM PF02971; match to protein family HMM PF07837; match to protein family HMM TIGR02024.
