| Glossary: |
dopamine = 4-(2-aminoethyl)benzene-1,2-diol |
| Other name(s): |
deacetylisoipecoside dopamine-lyase |
| Systematic name: |
deacetylisoipecoside dopamine-lyase (secologanin-forming) |
| Comments: |
The enzyme from the leaves of Alangium lamarckii differs in enantiomeric specificity from EC 4.3.3.4 deacetylipecoside synthase. The product is rapidly converted to demethylisoalangiside. |
