Enzyme Information
| 3.1.4.1 |
Phosphodiesterase I.
based on mapping to UniProt P06802
Hydrolytically removes 5'-nucleotides successively from the 3'-hydroxy termini of 3'-hydroxy-terminated oligonucleotides.
-!- Hydrolyzes both ribonucleotides and deoxyribonucleotides. -!- Has low activity toward polynucleotides. -!- A 3'-phosphate terminus on the substrate inhibits hydrolysis.
|
| 3.6.1.9 |
Nucleotide diphosphatase.
based on mapping to UniProt P06802
A nucleoside triphosphate + H(2)O = a nucleotide + diphosphate.
-!- The enzyme preferentially hydrolyzes ATP, but can also hydrolyze other nucleoside 5' triphosphates such as GTP, CTP, TTP and UTP to their corresponding monophosphates. -!- In vitro the enzyme also acts as a nucleotidohydrolase on ADP, NAD(+), NADP(+), FAD, and CoA. -!- Formerly EC 3.6.1.19.
