For an L1 to be a bona fide progenitor element of a L1-TD, it must be longer than, or of the same length as, the L1 element of the L1-TD.
However, theophylline was toxic to bacteria, and caused a decrease in the growth of bacteria containing the parental td intron at concentrations greater than 0.5 mM.
Group I aptazymes that were dependent upon theophylline both in vitro and in vivo were engineered by conjoining the thymidylate synthase ( td ) intron with an anti-theophylline aptamer.
For example, the junction between the aptamer and the Group I ribozyme in the aptazyme Th2P6 resembled the deletion variant td ΔP6-6; the aptazyme was activated by theophylline, while the splicing defect of the deletion variant at 3 mM magnesium was suppressed by 8 mM magnesium or by stabilization of a tetraloop sequence that capped the P6 helix [ 15 ] . Defects that poise a ribozyme between active and inactive conformers have previously been used to engineer effector-dependence [ 20 ] .
Magnesium had previously been shown to suppress structural defects in the td intron, and ligand-induced suppressions of splicing defects were examined by carrying out splicing reactions at either low (3 mM, stringent) or high (8 mM, permissive) magnesium concentrations [ 15 ] . Several of the constructs were either relatively inactive (e.g.
