Abstract
Bacillus globigii contains two site-specific endonucleases, BPGLI AND BglI. A rapid technique for selection of mutants deficient in each of these enzymes was developed using sensitivity to infection by bacteriophage SP50 as an indication of the levels of enzyme. Mutants defective in BglI, BglII, and both BglI and BglII retained the wild-type modification phenotype. Genetic and biochemical studies have established that these enzymes are involved in restriction in vivo. Simplified purification procedures for BglI and BglII using these mutants are described.Entities:
