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

Score
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. (274 aa)    
Predicted Functional Partners:
folA
Dihydrofolate reductase type I; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
 
 0.998
dut
dUTP pyrophosphatase (Deoxyuridine 5'-triphosphate nucleotidohydrolase); 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; Belongs to the dUTPase family.
  
 0.966
tdk
Similar to Q87QJ8 Thymidine kinase from Vibrio parahaemolyticus (192 aa). FASTA: opt: 629 Z-score: 820.6 E(): 8.2e-38 Smith-Waterman score: 629; 46.465identity in 198 aa overlap.
  
 
 0.962
nupC2
Thymidylate kinase; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family.
  
 
 0.945
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.
  
 
 0.933
gcvT
Glycine cleavage complex protein T (aminomethyltransferase); The glycine cleavage system catalyzes the degradation of glycine.
    
 0.928
folD
Methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
  
 
 0.926
folC
Similar to Q8ECR5 FolC bifunctional protein from Shewanella oneidensis (431 aa). FASTA: opt: 507 Z-score: 630.2 E(): 3.3e-27 Smith-Waterman score: 627; 32.274 identity in 409 aa overlap.
     
 0.867
lgt
Prolipoprotein diacylglyceryl transferase; Catalyzes the transfer of the diacylglyceryl group from phosphatidylglycerol to the sulfhydryl group of the N-terminal cysteine of a prolipoprotein, the first step in the formation of mature lipoproteins; Belongs to the Lgt family.
  
  
 0.847
serA
Similar to Q8EIH7 D-3-phosphoglycerate dehydrogenase from Shewanella oneidensis (409 aa). FASTA: opt: 1616 Z-score: 1931.0 E(): 1.1e-99 Smith-Waterman score: 1616; 59.756identity in 410 aa overlap; Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
