ENZYME entry: EC 1.3.1.105
Accepted Name |
2-methylene-furan-3-one reductase.
|
Alternative Name(s) |
Enone oxidoreductase. |
Reaction catalysed |
4-hydroxy-2,5-dimethylfuran-3(2H)-one + NADP(+) <=> 4-hydroxy-5-methyl-2-methylenefuran-3(2H)-one + NADPH |
Comment(s) |
- The enzyme was dicovered in strawberry (Fragaria x ananassa), where
it produces furaneol, one of the major aroma compounds in the fruits.
- It has also been detected in tomato (Solanum lycopersicum) and
pineapple (Ananas comosus).
- The enzyme can also act on derivatives substituted at the methylene
functional group.
- The enzyme from the yeast Saccharomyces cerevisiae acts on (2E)-2-
ethylidene-4-hydroxy-5-methylfuran-3(2H)-one and produces
homofuraneol, an important aroma compound in soy sauce and miso.
- NADPH is the preferred cofactor.
