Abstract

Methylation of DNA can be a critical step in the introduction of DNA into P. haemolytica. A methyltransferase has been isolated and molecularly cloned for this purpose. Use of the methyltransferase has allowed construction of defined, attenuated mutants for use as vaccines to protect cattle.
