... Y8 2TAA are in orange Other binding residues (W9AMY2, H92AMY2, T94AMY2, A9 5AMY2, Y1 30AMY2, A1 45AMY2, F180AMY2, K182AMY2, W206AMY2, S208AMY2, Y2 11AMY2, H288AMY2, Q294AMY2, M296AMY2 and Q35TAA, H 122 TAA, ... The superimpositioning was guided by the catalytic acids (D179AMY2, E204AMY2, and D289AMY2 and D206TAA, E230TAA, and D297TAA) The invariant Y5 1AMY2 and Y8 2TAA are at subsite )1 as are H92AMY2 ... glucosyl at subsite )2 [17] and in contrast to Tyr51AMY2 and Tyr82TAA, the geometry differed of the Met52AMY2 (Met53AMY1) and Trp83TAA (Fig 1A) Also the larger TAA loop in TAA appeared to hinder binding...
