From: Effect of attC structure on cassette excision by integron integrases
Excision percentage of sat cassette by the IntI1, IntI3, IntI2*179E and SonIntIA integron integrases. For each integrase, the bars indicate the excision percentage determined in the in vivo quantitative excision tests. Excision percentages correspond to the average of two independent assays. We tested the excision percentage of the gene cassette sat2 [pLQ430 and several mutants (A: first set of mutants and B: second set of mutants) created from the clone pLQ430 carrying the attC dfrA1 + sat2 cassette] coding for streptothricin resistance. The ‡ indicates that the first extrahelical base is located on the opposite side of the folded bottom strand structure. Error bars show standard error.
