Application
HpaI is a restriction endonuclease that is used to cleave DNA at the recognition site 5′-GTT/AAC-3′, generating fragments with blunt ends.
Biochem/physiol Actions
Recognition sequence: 5′-GTT/AAC-3′
Ligation and recutting results: After 2-10-fold Hpa I overdigestion of 1 μg λ DNA substrate, results in 100% cutting, >80% of fragments can be ligated, and >95% recut.
Heat inactivation: Not completely inactivated at 65 °C for 15 minutes.
