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

thyAThymidylate 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. (263 aa)    
Predicted Functional Partners:
DfrA
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
 
 
 0.997
Dut
Putative dUTP diphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
  
 0.963
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.
  
 
 0.938
RibD_1
Cytidine and deoxycytidylate deaminase zinc-binding region; KEGG: vpr:Vpar_0963 1.8e-81 CMP/dCMP deaminase zinc-binding protein; K01493 dCMP deaminase.
  
 
 0.934
folD
Tetrahydrofolate dehydrogenase/cyclohydrolase, NAD(P)-binding domain protein; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
  
 
 0.929
MetF
Homocysteine S-methyltransferase/5,10-methylenetetrahydrofolate reductase domain protein; KEGG: mas:Mahau_0258 1.6e-66 homocysteine S-methyltransferase; K00547 homocysteine S-methyltransferase; Psort location: Cytoplasmic, score: 8.96; Belongs to the methylenetetrahydrofolate reductase family.
     
 0.924
surE
SurE-like protein; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
   
 
 0.911
YfbR
HD domain protein; KEGG: vpr:Vpar_0282 1.1e-83 metal dependent phosphohydrolase; K08722 5'-nucleotidase; Psort location: Cytoplasmic, score: 8.96.
     
  0.900
Fgs
Protein FolC; KEGG: vpr:Vpar_1251 6.1e-209 bifunctional folylpolyglutamate synthase/dihydrofolate synthase; K11754 dihydrofolate synthase / folylpolyglutamate synthase; Psort location: Cytoplasmic, score: 9.97.
     
 0.849
NrdA
Ribonucleoside-diphosphate reductase, alpha subunit; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
