Abstract

Escherichia coli - enzymology DNA Replication Bacillus subtilis - enzymology Bacteriophage lambda - physiology DNA - metabolism Exodeoxyribonuclease V Plasmids - metabolism Bacillus subtilis - genetics Phenotype Time Factors Escherichia coli - genetics Recombination, Genetic Gene Deletion Exodeoxyribonucleases - physiology Bacteriophage lambda - genetics Exodeoxyribonucleases - genetics Mutation Rec A Recombinases - genetics
When expressed in Escherichia coli, the AddAB exonuclease/recombinase from Bacillus subtilis blocks the growth of phage lambda. Mutants of lambda that are deleted for ea47, a gene of unknown function which is expressed early in the lytic cycle, are not blocked for growth. The blocked-growth phenotype of lambda ea47+ in the presence of AddAB is expressed only when phage DNA replication is permitted.
