title: Comparison of two methods of genetic exchange in determination of the genetic locus of the structural gene for Pseudomonas aeruginosa elastase.
abstract: A mutation, lasA1, that results in the synthesis of enzymatically inactive elastase protein was mapped by R68.45 plasmid-mediated conjugation and transposon-facilitated recombination to ca. 75 min on the Pseudomonas aeruginosa PAO chromosome. Since immunologically cross-reactive material is produced, the mutation presumably arose within the elastase structural gene.
