DEFINITION

Classification: 435/478

Plasmid or episome contains at least part of a gene encoding a restriction endonuclease or modification enzyme:

(under subclass 476) Processes wherein at least part of a gene for a restriction endonuclease or at least part of a gene for a modification enzyme is present on the plasmid or episome.

(1) Note. A restriction endonuclease cleaves DNA at a site possessing a defined nucleotide pattern. A modification enzyme methylates or otherwise modifies DNA at sites possessing specific nucleotide patterns thereby preventing cleavage by a particular restriction endonuclease.

(2) Note. This subclass does not include the use of genes encoding endonucleases or methylases which are not involved in restriction and modification.
