3α(S)-strictosidine β-glucosidase (EC 3.2.1.105) is an enzyme with systematic name strictosidine β-D-glucohydrolase.[1][2][3] It catalyses the following chemical reaction:

strictosidine + H2O [math]\displaystyle{ \rightleftharpoons }[/math] D-glucose + strictosidine aglycone

It belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. It participates in indole and ipecac alkaloid biosynthesis.

Strictosidine is a precursor of indole alkaloids.
