A Mutant of Pseudomonas aeruginosa Deficient in an ATP-dependent Deoxyribonuclease

Abstract
A mutant of P. aeruginosa PAO1 originally isolated on the basis of its sensitivity to methyl methanesulfonate was sensitive to UV- and .gamma.-irradiation, deficient in recombination as assayed by transduction and conjugation and deficient in an ATP-dependent deoxyribonuclease activity. Its marker (mms-13) is cotransducible with argB and pyrE which are mapped at approximately 22 min on the P. aeruginosa chromosome.
