Aldos-2-ulose dehydratase

Template:Infobox enzyme Aldos-2-ulose dehydratase (Template:EnzExplorer, pyranosone dehydratase, AUDH, 1,5-anhydro-D-fructose dehydratase (microthecin-forming)) is an enzyme with systematic name 1,5-anhydro-D-fructose hydro-lyase (microthecin-forming). This enzyme catalyses the following chemical reaction

1,5-anhydro-D-fructose $\rightleftharpoons$ 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one + H₂O (overall reaction)

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

(1b) 1,5-anhydro-4-deoxy-D-glycero-hex-3-en-2-ulose $\rightleftharpoons$ 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one

This enzyme catalyses two of the steps in the anhydrofructose pathway.
