1,5-anhydro-D-fructose dehydratase

In enzymology, a 1,5-anhydro-D-fructose dehydratase is an enzyme that catalyzes the chemical reaction


 * 1,5-anhydro-D-fructose $$\rightleftharpoons$$ 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose + H2O

Hence, this enzyme has one substrate, 1,5-anhydro-D-fructose, and two products, 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose and H2O.

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 1,5-anhydro-D-fructose hydro-lyase (ascopyrone-M-forming). Other names in common use include 1,5-anhydro-D-fructose 4-dehydratase, 1,5-anhydro-D-fructose hydrolyase, 1,5-anhydro-D-arabino-hex-2-ulose dehydratase, AFDH, AF dehydratase, and 1,5-anhydro-D-fructose hydro-lyase.
