CC   -!- FUNCTION: A P subtype restriction enzyme that recognizes the double-
CC       stranded sequence 5'-GTNNAC-3'; the cleavage site is unknown.
CC       {ECO:0000303|PubMed:12654995}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage of DNA to give specific double-
CC         stranded fragments with terminal 5'-phosphates.; EC=3.1.21.4;
