Accepted name: synephrine dehydratase
Reaction: (R)-synephrine = (4-hydroxyphenyl)acetaldehyde + methylamine
Glossary: (R)-synephrine = D-(-)-synephrine = 4-[(1R)-1-hydroxy-2-(methylamino)ethyl]phenol
Other name(s): syringinase
Systematic name: (R)-synephrine hydro-lyase (methylamine-forming)
Comments: Removal of H2O from (R)-synephrine produces a 2,3-enamine, which hydrolyses to the products shown in the reaction above. The enzyme from Arthrobacter synephrinum is highly specific [1].
