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

dhfrIIIDihydrofolate reductase type 3; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. (163 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.
 
 
 0.998
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.
  
 
 0.946
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.
  
 
 0.938
folC
Bifunctional protein folC [Includes: Folylpolyglutamate synthase; Dihydrofolate synthase]; Belongs to the folylpolyglutamate synthase family.
     
 0.935
gcvT
Aminomethyltransferase; The glycine cleavage system catalyzes the degradation of glycine.
  
 
 0.926
purH
Bifunctional purine biosynthesis protein purH [Includes: Phosphoribosylaminoimidazolecarboxamide formyltransferase; IMP cyclohydrolase].
    
 0.925
phhA
Phenylalanine-4-hydroxylase.
     
 0.900
pdxA
4-hydroxythreonine-4-phosphate dehydrogenase; Catalyzes the NAD(P)-dependent oxidation of 4-(phosphooxy)-L- threonine (HTP) into 2-amino-3-oxo-4-(phosphooxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP).
     
 0.838
folK
2-amino-4-hydroxy-6- hydroxymethyldihydropteridinepyrophosphokinase.
    
 0.809
surA
Chaperone surA; Chaperone involved in the correct folding and assembly of outer membrane proteins. Recognizes specific patterns of aromatic residues and the orientation of their side chains, which are found more frequently in integral outer membrane proteins. May act in both early periplasmic and late outer membrane-associated steps of protein maturation.
