title: Three restriction endonucleases from Anabaena flos-aquae.
abstract: Three site-specific endonucleases, AflI, AflII and AflIII, have been partially purified from the cyanobacterium Anabaena flos-aquae CCAP 1403/13f. Their recognition and cleavage specificities have been determined to be: (formula; see text) AflII and AflIII are new specificities and may be useful in molecular cloning, as well as in the analysis of DNA. The distribution of type II restriction endonucleases in the cyanobacteria is briefly discussed.
