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

folCFolylpolyglutamate synthase/dihydrofolate synthase (folC); Functions in two distinct reactions of the de novo folate biosynthetic pathway. Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate or 10- formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to folylpolyglutamate derivatives. (437 aa)    
Predicted Functional Partners:
folP-A
Dihydropteroate synthase (folP-1); Catalyzes the condensation of para-aminobenzoate (pABA) with 6-hydroxymethyl-7,8-dihydropterin diphosphate (DHPt-PP) to form 7,8- dihydropteroate (H2Pte), the immediate precursor of folate derivatives.

HI_1464
Dihydropteroate synthase (folP-2); Similar to GB:L06494 SP:P26282 GB:U01376 GB:X68776 GB:X68777 percent identity: 54.15; identified by sequence similarity; putative.
 
 0.942
folK
2-amino-4-hydroxy-6- hydroxymethyldihydropteridine-pyrophosphokinase (folK); Similar to GB:D26562 SP:P26281 GB:L06495 PID:146013 PID:473801 percent identity: 56.33; identified by sequence similarity; putative.
 
 
 0.868
accD
acetyl-CoA carboxylase carboxyl transferase subunit beta (accD); Component of the acetyl coenzyme A carboxylase (ACC) complex. Biotin carboxylase (BC) catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the transcarboxylase to acetyl-CoA to form malonyl-CoA; Belongs to the AccD/PCCB family.
  
  
 0.863
folB
Dihydroneopterin aldolase, putative; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin. Can use L-threo-dihydroneopterin and D-erythro-dihydroneopterin as substrates for the formation of 6- hydroxymethyldihydropterin, but it can also catalyze the epimerization of carbon 2' of dihydroneopterin to dihydromonapterin.
  
 
 0.851
folA
Dihydrofolate reductase (folA); Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity); Belongs to the dihydrofolate reductase family.
     
 0.839
folE
GTP cyclohydrolase I (folE); Similar to GB:U00007 SP:P27511 GB:X63910 PID:312964 PID:405902 percent identity: 63.93; identified by sequence similarity; putative.
 
  
 0.737
coaBC
DNA/pantothenate metabolism flavoprotein (dfp); Catalyzes two sequential steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'- phosphopantothenate to form 4-phosphopantothenoylcysteine. In the second step the latter compound is decarboxylated to form 4'- phosphopantotheine; In the C-terminal section; belongs to the PPC synthetase family.
     
 0.732
glyA
Serine hydroxymethyltransferase (serine methylase) (glyA); 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.
  
 0.707
thyA
Thymidylate synthetase (thyA); 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.
