1,5-anhydro-D-fructose dehydratase

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.
