Fig. 7: Comparative analysis of natural and mutant FMN aptamers.

Sequence alignment of the selected natural FMN aptamers with the mutant aptamer M11 and M15. Mutations at nucleotide positions (i) G11, G12, G62, and G84 are shown in red, and (ii) nucleotides involved in the G-G non-canonical base pairing G10 and G47 are shown in blue.
