== Function ==
[https://www.uniprot.org/uniprot/BACE1_HUMAN 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.<ref>PMID:10677483</ref> <ref>PMID:20354142</ref>

== Publication Abstract from PubMed ==
The hydroxyethylene octapeptide inhibitor OM99-2 served as starting point to create the tripeptide inhibitor 1 and its analogues 2a and b. An X-ray co-crystal structure of 1 with BACE-1 allowed the design and syntheses of a series of macrocyclic analogues 3a-h covalently linking the P1 and P3 side-chains. These inhibitors show improved enzymatic potency over their open-chain analogue. Inhibitor 3h also shows activity in a cellular system.
