title: TspGWI, a thermophilic class-IIS restriction endonuclease from Thermus sp., recognizes novel asymmetric sequence 5'-ACGGA(N11/9)-3'.
abstract: A novel prototype class-IIS restriction endonuclease, TspGWI, was isolated from the thermophilic bacterium Thermus sp. GW. The recognition sequence and cleavage positions have been established: TspGWI recognizes the non-palindromic 5-bp sequence 5'-ACGGA-3' and cleaves the DNA 11 and 9 nt downstream in the top and bottom strand, respectively. In addition, an accompanying endonuclease, TspGWII, an isoschizomer of Pst I, was found in Thermus sp. GW cells.
