Function

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.[1] [2]

Publication Abstract from PubMed

BACE-1 is a flexible enzyme with experimentally determined motion in the flap region, the catalytic aspartates, and the 10s loop. Four in-house crystallographically determined complexes of tertiary carbinamine inhibitors revealed 10s loop motion in the S(3) pocket. These X-ray structures were used to correlate K(i) values, which span over five orders of magnitude, with the calculated interaction energy, using the Merck Molecular Force Field for a series of 19 tertiary carbinamine inhibitors.
