ID 1.3.1.105 DE 2-methylene-furan-3-one reductase. AN enone oxidoreductase. CA 4-hydroxy-2,5-dimethyl-furan-3(2H)-one + NADP(+) = 4-hydroxy-5-methyl-2- CA methylenefuran-3(2H)-one + H(+) + NADPH. CC -!- The enzyme was dicovered in strawberry (Fragaria x ananassa), where CC it produces furaneol, one of the major aroma compounds in the fruits. CC -!- It has also been detected in tomato (Solanum lycopersicum) and CC pineapple (Ananas comosus). CC -!- The enzyme can also act on derivatives substituted at the methylene CC functional group. CC -!- The enzyme from the yeast Saccharomyces cerevisiae acts on (2E)-2- CC ethylidene-4-hydroxy-5-methylfuran-3(2H)-one and produces CC homofuraneol, an important aroma compound in soy sauce and miso. CC -!- NADPH is the preferred cofactor. DR Q941I0, ENOXC_FRAAN; Q84V25, ENOXE_FRAAN; O23939, ENOX_FRAVE ; DR K4BW79, ENOX_SOLLC ; //
