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.

Slit_2522Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. (177 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.

Slit_2111
TIGRFAM: FolC bifunctional protein; KEGG: mei:Msip34_1543 FolC bifunctional protein; PFAM: Mur ligase middle domain protein; cytoplasmic peptidoglycan synthetase domain protein; Belongs to the folylpolyglutamate synthase family.
     
 0.932
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.
  
 
 0.913
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.
    
 0.907
purU
Formyltetrahydrofolate deformylase; Catalyzes the hydrolysis of 10-formyltetrahydrofolate (formyl-FH4) to formate and tetrahydrofolate (FH4).
     
 0.903
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.
   
 
 0.903
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.
    
 0.902
Slit_0168
PFAM: short-chain dehydrogenase/reductase SDR; KEGG: nmu:Nmul_A0336 pteridine reductase.
     
 0.901
gcvT
Glycine cleavage system T protein; The glycine cleavage system catalyzes the degradation of glycine.
     
 0.901
Slit_2521
PFAM: S23 ribosomal protein; KEGG: tbd:Tbd_0653 hypothetical protein.
