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

tmkPutative thymidylate kinase; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family. (205 aa)    
Predicted Functional Partners:
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.
 
  
 0.938
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.
  
 
 0.934
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.
  
 
 0.932
nrdE
Ribonucleoside-diphosphate reductase alpha chain; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides.
  
 
 0.927
ndk
Putative nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
    
 0.918
nrdF1
Ribonucleotide reductase beta-chain 1; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides; Belongs to the ribonucleoside diphosphate reductase small chain family.
   
 
 0.908
nrdF2
Similar to Escherichia coli ribonucleoside-diphosphate reductase 2 beta chain NrdF SW:RIR4_ECOLI (P37146) (319 aa) fasta scores: E(): 5.4e-72, 56.74% id in 319 aa, and to Mycobacterium leprae ribonucleoside-diphosphate reductase beta chain ML1731 SW:RIR2_MYCLE (Q9CBQ2) (325 aa) fasta scores: E(): 1.5e-74, 61.12% id in 319 aa. Note: Also similar to DIP1865 (328 aa) fasta scores: E(): 5.7e-71, 54.799% identity in 323 aa overlap.
   
 
 0.908
ahcY
Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.
       0.842
DIP0333
Similar to Mycobacterium tuberculosis CDC1551 DNA polymerase III, delta' subunit MT3747 TR:AAK48107 (EMBL:AE007173) (404 aa) fasta scores: E(): 1.4e-57, 46.59% id in 397 aa, and to Escherichia coli DNA polymerase III, delta' subunit HolB or B1099 SW:HOLB_ECOLI (P28631) (334 aa) fasta scores: E(): 6.9e-11, 28.61% id in 304 aa.

mtrA2
Putative two component system response regulator; Similar to Mycobacterium tuberculosis MtrA protein or Rv3246c or MTCY20B11.21c TR:Q50447 (EMBL:Z95121) (228 aa) fasta scores: E(): 7.6e-61, 70.66% id in 225 aa, and to Streptomyces coelicolor transcriptional regulatory protein AfsQ1 or 2SCK8.33c SW:AFQ1_STRCO (Q04942) (225 aa) fasta scores: E(): 2.4e-36, 45.2% id in 219 aa.
