Predicted primary and secondary structure of BGlluviae Immunity Repressor protein. Highlighted residues indicate the location of potential helices as predicted by PSIPRED (Buchan et al., 2013). Rectangles indicate the location of different helix-turn-helix domains and motifs identified via the Conserved Domains Database (Lu et al., 2020) and Protein Data Bank (Berman et al., 2000). The Ile54Thr substitution (red triangle) identified between BGlluviae phages isolated from turbid and clear plaques interrupts helix 4, found within the protein dimerization motif. For reference, also shown are additional missense substitutions found within the Immunity Repressor at residues 23, 55, and 71 (blue triangles) of clear strains of the mycobacteriophage Adephagia (Petrova et al., 2015)
