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

APW47041.1Bifunctional tetrahydrofolate synthase/dihydrofolate synthase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the folylpolyglutamate synthase family. (438 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.
 
 0.993
folA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
     
 0.935
APW47040.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
    0.896
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.
     
 0.871
purF
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine; In the C-terminal section; belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
  
 0.833
APW47039.1
Colicin V synthesis protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.818
guaA
Glutamine-hydrolyzing GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
  
 0.773
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.
  
 0.739
gltX
glutamate--tRNA ligase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu); Belongs to the class-I aminoacyl-tRNA synthetase family. Glutamate--tRNA ligase type 1 subfamily.
  
    0.738
folK
2-amino-4-hydroxy-6- hydroxymethyldihydropteridine diphosphokinase; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.712
