CD analysis of the effect of pH on the formation of i-motif structures. aBmPOUM2 wild-type; bBmPOUM2 mutant; cBGIBMGA003213 wild-type; dBGIBMGA003213 mutant. The sequences of these DNA fragments are listed in Table 1. DNA oligonucleotide sequences were folded in Tris–TAE buffer at pH 5.00, 6.02, 7.13 and 8.00 before CD scanning from 200 to 360 nm. The wild-type and mutated sequences are shown in Table 1
