Accepted Name
Memapsin 1.
Alternative Name(s)
ASP1.
BACE2.
Beta-secretase.
Beta-site Alzheimer's amyloid precursor protein cleaving enzyme 2.
Beta-site APP-cleaving enzyme 2.
Down region aspartic protease.
Membrane-associated aspartic protease 1.
Reaction catalysed
Broad endopeptidase specificity. Cleaves Glu-Val-Asn-Leu-|-Asp-Ala-Glu-Phe in the Swedish variant of Alzheimer's amyloid precursor protein
Comment(s)
