moreover , we were able to disclose some novel properties of dna restriction-modification enzymes concerning the protection of dna recognition sequences in which only one strand can be methylated ( e.g. , type iii enzyme ecop15 ) and the primary resistance of ( unmethylated ) dna recognition sites towards type ii restriction endonuclease ecorii .
