ENZYME entry: EC 3.1.4.1

Accepted Name
Phosphodiesterase I.
Alternative Name(s)
5' nucleotide phosphodiesterase/alkaline phosphodiesterase I.
5'-exonuclease.
5'-NPDase.
5'-nucleotide phosphodiesterase.
5'-PDase.
5'-PDE.
5'-phosphodiesterase.
5'NPDE.
Alkaline phosphodiesterase.
Exonuclease I.
Nucleotide pyrophosphatase/phosphodiesterase I.
Oligonucleate 5'-nucleotidohydrolase.
Orthophosphoric diester phosphohydrolase.
PDE I.
Phosphodiesterase.
Reaction catalysed
Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides
Comment(s)
  • Hydrolyzes both ribonucleotides and deoxyribonucleotides.
  • Has low activity toward polynucleotides.
  • A 3'-phosphate terminus on the substrate inhibits hydrolysis.
