Excision and transposition of Tn5 upon insertion in the hha gene of Escherichia coli.

Canadian journal of microbiology - 1 Jul 1994

Badenas C, Madrid C, Juárez A

Abstract excerpt

We report the occurrence of Tn5 secondary transpositions in Escherichia coli HB101 hha::Tn5(pANN202-312). Tn5-induced hha mutants (hemolysin overproducers) segregated at high frequency either hemolysin-negative clones or clones showing the parental hemolytic phenotype (reduced hemolysin production). Secondary transpositions of Tn5 appeared to be responsible for the phenotypes of both types of derivatives. The...
