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

folCFolC bifunctional protein; 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. (422 aa)    
Predicted Functional Partners:
folP
Dihydropteroate synthase; 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.
 
 0.998
folA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity).
     
 0.966
ydgB
Hypothetical oxidoreductase ydgB; Catalyzes the reduction of dihydromonapterin to tetrahydromonapterin. Also has lower activity with dihydrofolate.
   
 
 0.910
dedD
DedD protein; Non-essential cell division protein that could be required for efficient cell constriction.
  
  
 0.886
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. Belongs to the thymidylate synthase family. Bacterial-type ThyA subfamily.
     
 0.860
folK
2-amino-4-hydroxy-6- hydroxymethyldihydropteridine pyrophosphokinase; Escherichia coli K-12 ortholog: b0142; Escherichia coli O157:H7 ortholog: z0153.
 
  
 0.847
folE
GTP cyclohydrolase I; Escherichia coli K-12 ortholog: b2153; Escherichia coli O157:H7 ortholog: z3409.
 
  
 0.843
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
  
 0.803
ygiG
Dihydroneopterin aldolase; 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 at appreciable velocity.
  
  
 0.788
truA
tRNA pseudouridine synthase A; Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs.
 
   
 0.784
