2-methylene-furan-3-one reductase.
based on mapping to UniProt O23939
4-hydroxy-2,5-dimethylfuran-3(2H)-one + NADP(+) = 4-hydroxy-5-methyl-2- methylenefuran-3(2H)-one + NADPH.
-!- 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.
