A suicide plasmid, pExp1-ctpA::tetM-recAec, employing recA from Escherichia coli and tetM as a selection marker, was used to generate ctpA knockout mutants in Mycoplasma mycoides subsp. capri through targeted gene disruption. Inclusion of E. coli recA greatly enhanced both the consistency and the recovery of mutants generated by homologous recombination.
