The pharmacological evidence compiled for y-secretase is indicative of the activity of an aspartic protease requiring at least one additional cofactor. The location of the active site within the membrane makes y-secretase quite unique. Currently, there is only one precedent for a similar, tricky enzyme, signal peptidase, which shares several features and most of the problems associated with inner-membrane location [25]. It will not, unfortunately, be easy to isolate and purify the membrane-stabilized protease while retaining its activity. It has, therefore, so far escaped crystallization and X-ray structure determination. Mutation analysis of the two conserved aspartic acids of all presenilins supports their key role in y-secretase... [Pg.267]

More recently, the principles for designing inhibitors of aspartic proteases have been applied to the design of inhibitors of j8-secretase (BACEor Memapsin-2)as potential agents for treating or preventing Alzheimer s disease (95, 96). Both statine-derived inhibitors (43) and hydro3 ethylene-derived BACE inhibitors have been reported (Fig. 15.21)07,98). A crystal structure of (44) bound to j3-secretase has been reported (99). As expected, the hy-... [Pg.649]

More recently, the substrate specificity of /9-secretase has been explored and compared with that of other aspartic proteases using a range of dodecameric substrates based mainly on the j3 -cleavage site of APP (67). The substrate recognition site of /3-secretase extended over several amino acids, and /9-secretase accepted a wide range of peptidic substrates. In common with other aspartic proteases, /9-secretase prefers a leucine residue at position PI. However, unlike these enzymes, /3-sccrctasc accepts polar or even acidic residues at positions PI and P2. and prefers bulky hydrophobic residues, preferably valine, at position P3. [Pg.555]

Alzheimer s disease is characterized by plaques in the brain consisting primarily of the 40-42 amino acid amyloid / -peptide (A/ ) [258]. AfS derives from proteolysis of the amyloid precursor protein (APP) by the fS and y sec-retases to create the N and C-termini of the peptide respectively [259]. The / -secretase has recently been identified as a 501 amino-acid transmembrane protein by several research groups [260-263], The enzyme, variously named BACE, memapsin2, and Asp2, is an aspartic protease related to pepsin, cathepsin D, and renin, with all the properties expected of the /i-sccrctasc. [Pg.206]
