Function

[BACE1_HUMAN] Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase.^[1] ^[2]

Publication Abstract from PubMed

The structure of the catalytic domain of human memapsin 2 bound to an inhibitor OM00-3 (Glu-Leu-Asp-LeuAla-Val-Glu-Phe, K(i) = 0.3 nM, the asterisk denotes the hydroxyethylene transition-state isostere) has been determined at 2.1 A resolution. Uniquely defined in the structure are the locations of S(3)' and S(4)' subsites, which were not identified in the previous structure of memapsin 2 in complex with the inhibitor OM99-2 (Glu-Val-Asn-LeuAla-Ala-Glu-Phe, K(i) = 1 nM). Different binding modes for the P(2) and P(4) side chains are also observed. These new structural elements are useful for the design of new inhibitors. The structural and kinetic data indicate that the replacement of the P(2)' alanine in OM99-2 with a valine in OM00-3 stabilizes the binding of P(3)' and P(4)'.
