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. |
