Endodeoxyribonuclease

Endodeoxyribonuclease is an endonuclease ribonuclease.

Restriction enzymes are a type of endodeoxyribonuclease.

It is a restriction enzyme that chews up DNA at its ends. This is why DNA is not linear. For example, during Transduction in bacterial cells, bacteriophage DNA is inserted in a bacterial cell. The DNA from the bacteriophage immediately circularizes in order to avoid getting "chewed up" by endodeoxyribonuclease at their ends.
