Hydrolyzing N-glycosyl compounds.
based on mapping to UniProt Q8ZVK6
|
| 4.2.99.18 |
DNA-(apurinic or apyrimidinic site) lyase.
based on mapping to UniProt Q8ZVK6
The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.
-!- 'Nicking' of the phosphodiester bond is due to a lyase-type reaction, not hydrolysis. -!- This group of enzymes was previously listed as endonucleases, under the number EC 3.1.25.2.
