The cleavage site of the restriction endonuclease Ava II

Nucleic Acids Res. 1978 Jul;5(7):2313-9. doi: 10.1093/nar/5.7.2313.


We have determined that the type II restriction enzyme Ava II, isolated from Anabaena variabilis, recognizes and cuts the sequence (formula: see article). The eight Ava II sites of pBR322 have been mapped, as well as a unique site for Ava I.
