Abstract

We have purified AfaI endonuclease, an isoschizomer of RsaI, from Acidiphilium facilis strain 28H. The enzyme is homogeneous as judged by polyacrylamide gel electrophoresis, and composed of a single polypeptide chain with a molecular weight of 30 000. AfaI endonuclease, like RsaI, recognizes the tetranucleotide sequence 5′-G-T-A-C-3′, and cleaves between the T and A to produce blunt-ended fragments. The yield of the enzyme is 50-100-times that of the RsaI, which is form a phototrophic bacterium, Rhodospseudomonas sphaeroides strain 28/5.
