Table 1. Modes of integration of a mini-casposon encoding kanamycin resistance into pMA-Target catalyzed by tagged and de-tagged Cas1.
Enzyme | De-tagged Cas1 | Tagged Cas1 | ||
---|---|---|---|---|
Number of clones recovered | 129 ± 34a (2)b | 59 ± 19a (4)b | ||
Total number of clones sequenced | 9 | 28 | ||
Site of insertion | Insertion at the A. boonei target site | Insertion outside of the A. boonei target site | Insertion at the A. boonei TSD | Insertion outside of the A. boonei target site |
Number of clones sequenced | 4 clones | 5 clones | 26 clones | 2 clones |
Size of TSD at insertion site | 15 bp (2 clones) 4 bp (2 clones) | 16 bp (1 clone) 15 bp (1 clone) Unstable (1 clone) Deletion (2 clones) | 15 bp (26 clones) | 22 bp (1 clone) deletion (1 clone) |
anumber of clones ± standard deviation recovered per independent experiment.
bnumber of independent experiments (insertion + transformation).
Following transformation and selection for resistance to kanamycin, transformants were picked randomly and the regions flanking the left and right TIR were sequenced to determine the site of integration and the extent of sequence duplication occurring at the target site.
