title: A specific complex between a restriction endonuclease and its DNA substrate.
abstract: In the presence of Mg(++), ATP, and S-adenosylmethionine, the DNA restriction endonuclease R.K forms a specific complex with its DNA substrate. The complex can be detected by its retention on nitrocellulose membranes.
