    Thermo Fisher escherichia coli strains e coli strain dh5α
    ΦTE-F expresses ToxI RNA during infection. (A) Upper panel; an S1-nuclease protection assay was used to detect ToxI levels from a ToxIN plasmid during ΦTE wt infection, using an antisense probe against the full 5.5 repeat ToxI sequence [46] . The antisense ToxI-probe was first hybridised to 10 µg of total RNA prepared from Pba ToxIN (pMJ4) at different times after ΦTE infection, and then followed by S1-nuclease treatment. Numbers (+) indicate the time (min) after infection or (−) without the addition of phage. Pba ToxIN-FS (pTA47) and Pba serve as positive and negative controls, respectively. A non-hybridized S1-digested probe (+S1) serves as a further negative control. <t>DH5α</t> 1.5 repeats (pTA96), a non-S1 digested probe (−S1) and an in vitro transcribed Hammerhead ribozyme (HHRz), which cleaves itself during transcription, serve as size markers. HHRz was prepared as described previously [45] . Lower panel; Western blot targeting C-terminal FLAG tagged ToxN contained within total protein harvested from Pba ToxIN (pMJ4) at different time points, with (+, left) and without (−, right) phage infection. Time 0 indicates a sample taken immediately after infection. Total protein from Pba ToxIN (pMJ4) (−) serves as positive control. (B) Infection with escape phage ΦTE-F. Levels of ToxI were determined by S1-assay (upper) as described in (A) with and without infection. ToxN levels were estimated by Western blotting (lower) as described in (A). (C) Expression of the ΦTE-F ToxI locus. An S1-nuclease assay targeting ToxI was performed on total RNA of Pba (pBR322) at different times during ΦTE-F infection. Pba ToxIN (pMJ4) and DH5α serve as positive and negative controls, respectively.

    ΦTE-F expresses ToxI RNA during infection. (A) Upper panel; an S1-nuclease protection assay was used to detect ToxI levels from a ToxIN plasmid during ΦTE wt infection, using an antisense probe against the full 5.5 repeat ToxI sequence [46] . The antisense ToxI-probe was first hybridised to 10 µg of total RNA prepared from Pba ToxIN (pMJ4) at different times after ΦTE infection, and then followed by S1-nuclease treatment. Numbers (+) indicate the time (min) after infection or (−) without the addition of phage. Pba ToxIN-FS (pTA47) and Pba serve as positive and negative controls, respectively. A non-hybridized S1-digested probe (+S1) serves as a further negative control. DH5α 1.5 repeats (pTA96), a non-S1 digested probe (−S1) and an in vitro transcribed Hammerhead ribozyme (HHRz), which cleaves itself during transcription, serve as size markers. HHRz was prepared as described previously [45] . Lower panel; Western blot targeting C-terminal FLAG tagged ToxN contained within total protein harvested from Pba ToxIN (pMJ4) at different time points, with (+, left) and without (−, right) phage infection. Time 0 indicates a sample taken immediately after infection. Total protein from Pba ToxIN (pMJ4) (−) serves as positive control. (B) Infection with escape phage ΦTE-F. Levels of ToxI were determined by S1-assay (upper) as described in (A) with and without infection. ToxN levels were estimated by Western blotting (lower) as described in (A). (C) Expression of the ΦTE-F ToxI locus. An S1-nuclease assay targeting ToxI was performed on total RNA of Pba (pBR322) at different times during ΦTE-F infection. Pba ToxIN (pMJ4) and DH5α serve as positive and negative controls, respectively.

    Analysis of pseudo-ToxI as a potential antitoxin. (A) Alignment of the pseudo-ToxI and ToxI RNA sequences. Pseudo-ToxI nucleotides are coloured to match (B) and (C), with the green and purple bases denoting the 5′ and 3′ ends of a single pseudoknot, respectively. Mutated nucleotides in pseudo-ToxI are coloured orange and numbered according to their grouping, whilst the asterisk indicates the additional 3′ nucleotide. The dotted line connecting the U in group 3 indicates the uracil that is deleted in the case of expanded repeats with 2T sequences rather than 3T. (B) Schematic of the ToxI pseudoknot. Each position containing a mutation in the pseudo-ToxI RNA has been bracketed, with the ToxI base separated from the pseudo-ToxI base by a ‘/’. The mutations have been grouped 1–5, according to position, and highlighted in orange, with the 5′ and 3′ termini in green and violet, respectively. Indels, such as U17 that is deleted in some pseudo-ToxI repeats, and the additional A* inserted in all, have been bordered by a dashed line. Base interactions are indicated by black lines, and duplex and triplex base-interactions are bordered in grey. (C) Detail of the ToxIN trimer with each pseudoknot shown either in blue, purple or beige. Each ToxN monomer is shown as a grey surface. The blue pseudoknot is oriented relative to (B). The positions of mutation groups are shown, with the group number encircled in the same colour as the corresponding pseudoknot. The additional nucleotide of group 5 is not visible as this was not in the original solved ToxIN structure. PDB: 2XDB. (D) Pseudo-ToxI cannot protect from ToxN in an over-expression assay. Protection assays were conducted as per Materials and Methods using strains of E. coli DH5α carrying both pTA49 (inducible ToxN) and a second inducible antitoxin vector as shown, including use of pTA100 as a vector-only control, “vector”. Error bars indicate the standard deviation of triplicate data. (E) Protection assays using mutants of ToxI carried out as in (D) with the antitoxin mutations in each construct numbered as per (B). (F) Protection assays carried out as in (D), testing the full escape loci of ΦTE wt, ΦTE-A and ΦTE-F with full ToxI as a positive control. Under these conditions, there was sufficient antitoxin present to inhibit induced ToxN even without specific induction of the ToxI and ΦTE-F constructs.
