MeSH Heading: Phosphodiesterase I
Tree Number(s): D08.811.277.352.640.430
Unique ID: D043264
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D043264
Scope Note: A phosphoric diester hydrolase that removes 5'-nucleotides from the 3'-hydroxy termini of 3'-hydroxy-terminated OLIGONUCLEOTIDES. It has low activity towards POLYNUCLEOTIDES and the presence of 3'-phosphate terminus on the substrate may inhibit hydrolysis.
Entry Term(s): 5'-Exonuclease; 5'-Nucleotidephosphodiesterase; Alkaline Phosphodiesterase; Alkaline Phosphodiesterase I; Oligonucleate 5'-Nucleotidohydrolase; Orthophosphoric Diester Phosphohydrolase
Registry Number: EC 3.1.4.1
