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 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.
