Sysname
salutaridinol 7-O-acetate acetate-lyase (thebaine-forming)
Reaction(IUBMB)
salutaridinol 7-O-acetate = thebaine + acetate [RN:
R04769
]
Reaction(KEGG)
R04769
Reaction
Substrate
salutaridinol 7-O-acetate [CPD:
C05322
]
Product
thebaine [CPD:
C06173
];
acetate [CPD:
C00033

Comment
Isolated from the plant Papaver somniferum (opium poppy). The reaction occurs spontaneously when the pH is between 8-9, but the enzyme is required at the physiological pH, which is close to 7.
