Chains	Enzyme Name	Description	Catalytic Residues
A	strictosidine synthase M-CSA #360	Strictosidine synthase is an unusual six-bladed beta-propeller fold protein which catalyses the condensation of two precursor molecules, tryptamine and monoterpenoid secologanin to form strictosidine. This molecule is the generic starting material for the biosynthetic formation of monoterpenoid-derived indole alkaloids, many of which are known to have potent therapeutic characteristics, including anti-cancer properties.
