Nucleotide requirements in the anticodon loop. (A) Mutagenesis of hmtRNAThr at the non-Watson-Crick base pair (A29-C41; left), and mutagenesis of hmtRNAMet at the anticodon loop base (C34 and C38; right) are coloured red. (B) t6A modification levels of hmtRNAThr (black filled circles) and its mutants C32A (red filled squares), C32U (magenta filled triangles) and C32G (blue filled inverted triangles). (C) t6A modification levels of hmtRNAThr (black filled circles) and mutants U33A (red filled squares), U33C (cyanine filled triangles) and U33G (blue filled inverted triangles). (D) t6A modification levels of hmtRNAThr (black filled circles) and mutants U34A (red filled squares), U34C (cyanine filled triangles) and U34G (blue filled inverted triangles). (E) t6A modification levels of hmtRNAThr (black filled circles) and mutants G35A (red filled squares), G35C (cyanine filled triangles) and G35U (magenta filled inverted triangles). (F) t6A modification levels of hmtRNAMet (black filled circles) and mutants C34U (red filled squares), C38A (green filled triangles) and C34U/ C38A (magenta filled inverted triangles).
