Overproduction of the EcoR V endonuclease and methylase.

Abstract

Strains overproducing the EcoR V endonuclease and methylase have been obtained by inserting each of the two genes in expression vectors containing the lambda PL promoter. The methylase is overproduced to a level reaching 5-10% of the total cellular proteins, which represents a 50-100 fold increase. A 30 fold overproduction of endonuclease was achieved by randomly positioning the EndRV gene downstream of the lambda PL promoter. The situation in the endonuclease overproducing clone resembles that encountered in maxi-cells. The strains described here allowed a quick purification of both enzymes in sufficient amounts for crystallisation attempts.
