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.

Isop_2583COGs: COG0262 Dihydrofolate reductase; InterPro IPR001796: IPR017925: IPR003529: IPR012259; KEGG: aeh:Mlg_0423 dihydrofolate reductase; PFAM: dihydrofolate reductase region; PRIAM: Dihydrofolate reductase; SPTR: Dihydrofolate reductase; PFAM: Dihydrofolate reductase; Belongs to the dihydrofolate reductase family. (208 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.
 
 
 0.995
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.
  
 
 0.924
Isop_0668
Methionine synthase (B12-dependent); 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.
    
 0.922
fhs
Formate-tetrahydrofolate ligase; COGs: COG2759 Formyltetrahydrofolate synthetase; InterPro IPR000559: IPR020628; KEGG: amu:Amuc_1860 formate--tetrahydrofolate ligase; PFAM: formate-tetrahydrofolate ligase FTHFS; PRIAM: Formate--tetrahydrofolate ligase; SPTR: Formate--tetrahydrofolate ligase; PFAM: Formate--tetrahydrofolate ligase.

Isop_2273
FolC bifunctional protein; COGs: COG0285 Folylpolyglutamate synthase; InterPro IPR018109: IPR001645: IPR013221: IPR004101; KEGG: sti:Sthe_3030 FolC bifunctional protein; PFAM: Mur ligase middle domain protein; cytoplasmic peptidoglycan synthetase domain protein; PRIAM: Tetrahydrofolate synthase; SPTR: FolC bifunctional protein; TIGRFAM: FolC bifunctional protein; PFAM: Mur ligase family, glutamate ligase domain; Mur ligase middle domain; TIGRFAM: folylpolyglutamate synthase/dihydrofolate synthase.
     
 0.916
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; COGs: COG0138 AICAR transformylase/IMP cyclohydrolase PurH (only IMP cyclohydrolase domain in Aful); InterPro IPR011607: IPR013982: IPR002695; KEGG: plm:Plim_1423 phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; PFAM: AICARFT/IMPCHase bienzyme formylation region; MGS domain protein; PRIAM: Phosphoribosylaminoimidazolecarboxamide formyltransferase; SMART: AICARFT/IMPCHase bienzyme formylation region; SPTR: Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase [...]
    
 0.915
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.

gcvT
Glycine cleavage system T protein; The glycine cleavage system catalyzes the degradation of glycine.
    
 0.911
Isop_0230
Short-chain dehydrogenase/reductase SDR; COGs: COG1028 Dehydrogenase with different specificities (related to short-chain alcohol dehydrogenase); InterPro IPR002347: IPR002198; KEGG: plm:Plim_1577 short-chain dehydrogenase/reductase SDR; PFAM: short-chain dehydrogenase/reductase SDR; SPTR: Short-chain dehydrogenase/reductase SDR; PFAM: short chain dehydrogenase.
