6 × 10-7 CmRTpR transconjugants per TpR transconjugant, which is comparable to the copy-in activity of the unaltered IS26. To test for simple transposition of IS26catA1 (without the plasmid backbone), 1200 CmRTpR colonies were screened and all were resistant to ampicillin, indicating that the pUC19 backbone was present. Hence, IS26catA1 had only formed cointegrates. IS26 is unable to move alone and cointegrates are the exclusive end products of the reactions mediated by the IS26 transposase Tnp26. Consequently, when describin
