Endoproteolysis of β-amyloid precursor protein (βAPP) and Notch requires conserved
aspartate residues in presenilins 1 and 2 (PS1 and PS2). Although PS1 and PS2 have
therefore been proposed to be aspartyl proteases, no homology to other aspartyl proteases
has been found. Here we identify homology between the presenilin active site and polytopic
aspartyl proteases of bacterial origin, thus supporting the hypothesis that presenilins are
novel aspartyl proteases.
