Latest Patents

Katsuragi holds a patent for a production method for PvuI restriction endonuclease. This patent describes a recombinant vector that incorporates a chromosome DNA fragment containing a PvuI restriction endonuclease gene derived from Proteus vulgaris. The method involves transforming a host with the recombinant vector, cultivating the transformed host, and harvesting PvuI restriction endonuclease from the resulting culture. This innovative approach simplifies the purification process, as the transformed host produces PvuI alone, eliminating the need to remove PvuII during purification. Additionally, the productivity for nonspecific DNase is lower compared to conventional producer bacteria, making the removal of DNase easier and enhancing the overall production efficiency of PvuI.
