KEGG   ENZYME: 4.3.3.3Help
Entry
EC 4.3.3.3                  Enzyme                                 

Name
deacetylisoipecoside synthase;
deacetylisoipecoside dopamine-lyase
Class
Lyases;
Carbon-nitrogen lyases;
Amine-lyases
BRITE hierarchy
Sysname
deacetylisoipecoside dopamine-lyase (secologanin-forming)
Reaction(IUBMB)
deacetylisoipecoside + H2O = dopamine + secologanin [RN:R05750]
Reaction(KEGG)
Substrate
deacetylisoipecoside [CPD:C07304];
H2O [CPD:C00001]
Product
dopamine [CPD:C03758];
secologanin [CPD:C01852]
Comment
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.
History
EC 4.3.3.3 created 2000
