CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(R)-amygdalin + H2O = (R)-prunasin + D-glucose;
CC         Xref=Rhea:RHEA:14177, ChEBI:CHEBI:4167, ChEBI:CHEBI:15377,

CC   -!- SUBUNIT: Monomer.
CC   -!- DEVELOPMENTAL STAGE: Absent from maturing black cherry fruits until 6
CC       weeks after flowering. Then, concomitant with cotyledon development,
CC       the level of enzyme increases with specificity for embryonal tissues.
CC   -!- PTM: Glycosylated.
