A methylase, recognizes the double-stranded sequence 5'-GGCC-3', methylates C-3 on both strands, and protects the DNA from cleavage by the HaeIII endonuclease.
Belongs to the class I-like SAM-binding methyltransferase superfamily. C5-methyltransferase family.
A P subtype restriction enzyme that recognizes the double-stranded sequence 5'-GGCC-3' and cleaves after G-2.
