Descriptions
A couple of restriction endonucleases, Pla I and Pla II, have been purified from a filametous and thermophilic cyanobacterium, Phormidium lapideum. Pla I was proved to be an isoschizomer of Hae III to cleavage the site GG↓CC and was a monomeric protein that had a molecular weight of about 40 kilodaltons. Pla II was an isoschizomer of Nsp (7524) V to recognize the site TTCGAA and was estimated as a heterotetrameric protein (α_2β_2). Pla II has an apparent molecular mass of 176 kilodaltons and that of α subunit was 63 kilodaltons, β subunit 31 kilodaltons. Characteristics of Pla I and Pla II were investigated in comparison with that of the respective isoschizomers, Hae III and Nsp (7524) V.
