Beta-secretase 1 (BACE1)

Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of this A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, along with a corresponding cell-associated C-terminal fragment that's later released by gamma-secretase.

Cleaves APP with much more catalytic efficiency than for the wild-type. .
