Computational Insights into Substrate and Site Specificities, Catalytic Mechanism, and Protonation States of the Catalytic Asp Dyad of β-Secretase
Figure 2
(a) Time evolution of the topological distance between the Cα(Thr72) of flap tip and Cβ(Asp32) of catalytic dyad (violet: BACE1-compound 11, blue: BACE1-SW substrate, red: BACE1-WT substrate, and green: Apo BACE1). (b) Number of hydrogen bonds formed between the substrates and BACE1 (blue: BACE1-SW substrate, red: BACE1-WT substrate). (c) Interaction of the substrate Glu with the Arg307 of BACE1.
