[[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 ==
Fragment screening revealed that tyramine binds to the active site of the Alzheimer's disease drug target BACE-1. Hit expansion by selection of compounds from the Roche compound library identified tyramine derivatives with improved binding affinities as monitored by surface plasmon resonance. X-ray structures show that the amine of the tyramine fragment hydrogen-bonds to the catalytic water molecule. Structure-guided ligand design led to the synthesis of further low molecular weight compounds that are starting points for chemical leads.
