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. (270 aa)    
Predicted Functional Partners:
DIP0824
Putative folate reductase; Similar to Mycobacterium avium dihydrofolate reductase FolA TR:O30463 (EMBL:AF006616) (181 aa) fasta scores: E(): 2e-22, 46.1% id in 167 aa, and to Escherichia coli dihydrofolate reductase FolA or TmrA or B0048 SW:DYR_ECOLI (P00379) (159 aa) fasta scores: E(): 1.5e-13, 42.76% id in 152 aa.

thyX
Conserved hypothetical protein; 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 NADPH and FADH(2) as the reductant.
    
 0.988
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.
  
 
 0.978
dut
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.
  
 0.964
DIP1785
Mur ligase family protein; Similar to Mycobacterium tuberculosis folylpolyglutamate synthase Rv2447c TR:O53174 (EMBL:AL021246) (487 aa) fasta scores: E(): 1.2e-100, 57.46% id in 496 aa, and to Mycobacterium leprae folylpolyglutamate synthase ML1471 TR:Q9CBY8 (EMBL:AL583922) (485 aa) fasta scores: E(): 3.8e-96, 56.17% id in 470 aa.
     
 0.957
tmk
Putative thymidylate kinase; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family.
  
 
 0.932
folD
Methylenetetrahydrofolate dehydrogenase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
  
 
 0.923
DIP1611
Similar to Streptomyces lividans 5,10-methylenetetrahydrofolate reductase MetF SW:METF_STRLI (O54235) (307 aa) fasta scores: E(): 4.1e-41, 41.58% id in 303 aa, and to Escherichia coli 5,10-methylenetetrahydrofolate reductase MetF or B3941 SW:METF_ECOLI (P00394) (296 aa) fasta scores: E(): 9.2e-15, 33.65% id in 309 aa.
    
 0.915
DIP0823
Conserved hypothetical protein; Similar to Mycobacterium tuberculosis CDC1551 conserved hypothetical protein MT3292 TR:AAK47635 (EMBL:AE007142) (84 aa) fasta scores: E(): 4.4e-12, 48.1% id in 79 aa.

DIP0826
Putative sulfite synthesis related protein; Similar to Mycobacterium tuberculosis CysQ protein homolog or Rv2131c or MT2189 or MTCY270.37 SW:CYSQ_MYCTU (O06244) (267 aa) fasta scores: E(): 9.2e-23, 52.51% id in 259 aa.
