Endonuclease-free, protoplast-forming enzyme preparation and its application in fungal transformation.
An endonuclease-free, protoplast-forming enzyme complex was prepared from the "snail enzyme." The purified preparation has high protoplast-forming activity comparable to the crude enzyme complex without destroying circular plasmid DNA. Furthermore, a higher transformation rate was achieved by the application of the endonuclease-free enzyme complex in both yeast and filamentous fungal vector-host systems.
