Aldos-2-ulose dehydratase
From Wikipedia, the free encyclopedia
Aldos-2-ulose dehydratase (EC 4.2.1.110, 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).[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- 1,5-anhydro-D-fructose 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one + H2O (overall reaction)
- (1a) 1,5-anhydro-D-fructose 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 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one
