Abstract: | Abstract Extracts of the transformable cyanobacterial strain Anacystis nidulans R2 were analyzed for the presence of restriction endonuclease. One enzyme, Ani I, was found and determined to be sequence-specific on the basis of its ability to cleave several Bacillus plasmids at a limited number of sites. The activity of this enzyme is significantly reduced in extracts prepared from cell cultures grown at 38°C. |
