948557-12-8 Usage

Uses

4-Hydroxy-5-methyl-2-methylene-3(2H)-furanone is a highly reactive precursor to 4-hydroxy-2,5-dimethyl-3(2H)-furanone (H471020) the key flavor compound in strawberry fruit.

Check Digit Verification of cas no

The CAS Registry Mumber 948557-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,8,5,5 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 948557-12:
(8*9)+(7*4)+(6*8)+(5*5)+(4*5)+(3*7)+(2*1)+(1*2)=218
218 % 10 = 8
So 948557-12-8 is a valid CAS Registry Number.

Functional characterization of enone oxidoreductases from strawberry and tomato fruit

Klein, Dorothee,Fink, Barbara,Arold, Beate,Eisenreich, Wolfgang,Schwab, Wilfried

, p. 6705 - 6711 (2008/09/17)

Fragaria x ananassa enone oxidoreductase (FaEO), earlier putatively assigned as quinone oxidoreductase, is a ripening-induced, negatively auxin-regulated enzyme that catalyzes the formation of 4-hydroxy-2,5-dimethyl- 3(2H)-furanone (HDMF), the key flavor compound in strawberry fruit by the reduction of the α,β-unsaturated bond of the highly reactive precursor 4-hydroxy-5-methyl-2-methylene-3(2H)-furanone (HMMF). Here we show that recombinant FaEO does not reduce the double bond of straight-chain 2-alkenals or 2-alkenones but rather hydrogenates previously unknown HMMF derivatives substituted at the methylene functional group. The furanones were prepared from 4-hydroxy-5-methyl-3(2H)-furanone with a number of aldehydes and a ketone. The kinetic data for the newly synthesized aroma-active substrates and products are similar to the values obtained for an enone oxidoreductase from Arabidopsis thaliana catalyzing the α,β-hydrogenation of 2-alkenals. HMMF, the substrate of FaEO that is formed during strawberry fruit ripening, was also detected in tomato and pineapple fruit by HPLC-ESI-MSn and became 13C-labeled when D-[6-13C]-glucose was applied to the fruits, which suggested that a similar HDMF biosynthetic pathway occurs in the different plant species. With a database search (http://ted.bti.cornell.edu/ and http://genet.imb.uq.edu.au/Pineapple/), we identified a tomato and pineapple expressed sequence tag that shows significant homology to FaEO. Solanum lycopersicon EO (SIEO) was cloned from cDNA, and the protein was expressed in Escherichia coli and purified. Biochemical studies confirmed the involvement of SIEO in the biosynthesis of HDMF in tomato fruit.
