Memapsin 2.
based on mapping to UniProt P56817
Broad endopeptidase specificity. Cleaves Glu-Val-Asn-Leu-|-Asp-Ala-Glu- Phe in the Swedish variant of Alzheimer's amyloid precursor protein.
-!- Suggested to be the major 'beta-secretase' responsible for the cleavage of the beta-amyloid precursor protein to form the amyloidogenic beta-peptide that is implicated in the pathology of Alzheimer's disease. -!- Belongs to peptidase family A1.
