Identification
HMDB Protein ID HMDBP00008
Secondary Accession Numbers
  • 5236
Name 5'(3')-deoxyribonucleotidase, mitochondrial
Synonyms
  1. 5',3'-nucleotidase, mitochondrial
  2. Deoxy-5'-nucleotidase 2
  3. dNT-2
Gene Name NT5M
Protein Type Unknown
Biological Properties
General Function Involved in phosphatase activity
Specific Function Dephosphorylates specifically the 5' and 2'(3')-phosphates of uracil and thymine deoxyribonucleotides, and so protects mitochondrial DNA replication from excess dTTP. Has only marginal activity towards dIMP and dGMP.
Pathways
  • Nicotinate and nicotinamide metabolism
  • Purine metabolism
  • Pyrimidine metabolism
