Glc designates the glucose monomer within a maltooligosaccharide, numbered 1–4 from the non-reducing end of sugar. Bold residues denote the aromatic platform, and all other residues are involved in hydrogen-bonding with the glucose hydroxyl groups

Average K_d for α-cyclodextrin (αCD), maltoheptaose (M7), and glucosyl-α(1,6)-maltotriosyl-α(1,6)-maltotriose for each domain as reported in Cameron et al. [75]
