(A) CD spectra showing the formation of a G-quadruplex structure in genotype B wild-type PQS (GTB-WT-PQS) oligonucleotide. The mutated oligonucleotide (GTB-MUT-PQS) does not form a G-quadruplex structure. A ssDNA control (25mer) incapable of forming a G-quadruplex is taken as a negative control. (B) 1H NMR spectra of genotype B wild type (GTB-WT-PQS) and mutated (GTB-MUT-PQS) PQS oligonucleotide. Please see Supplementary File S3 Table S1 for sequence of the oligonucleotides.
