Sse91, a type II restriction endonuclease, has been isolated from Sporosarcina species 9D. The recognition sequence and cleavage point of restriction endonuclease Sse91 have been determined as 5'-decrease AATT-3'. The new enzyme is an isoschizomer of Tsp5091, but its optimal incubation temperature is 55 degrees C and it is inactivated at 65 degrees C for 20 min.
