16. EC 3.1.21.5
Large enzymes
Combination restriction-and-modification
Cleave outside of their recognition
sequences /20-30 base pairs after the
recognition site/
Require two recognition sequences in
opposite orientations within the same
DNA molecule
17. Cleave only normal and modified DNA
(methylated, hydroxymethylated and
glucosyl-hydroxymethylated bases).
Recognition sequences have not been well
defined
Cleavage takes place ~30 bp away from one
of the sites
18. generated by fusing a natural or engineered DNA
binding domain to a nuclease domain
can target large DNA sites (up to 36 bp)
can be engineered to bind to desired DNA
sequences
