CC   -!- FUNCTION: A P subtype restriction enzyme that recognizes the double-
CC       stranded sequence 5'-GRCGYC-3' and cleaves after R-2.
CC       {ECO:0000303|PubMed:12654995, ECO:0000305|PubMed:2020544}.
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;
