AF029: Zn-containing dehydrogenase

List allergens from this family:

Routes of exposure:
Include only IUIS approved allergens.

Biochemical properties

Zinc-containing alcohol dehydrogenases are found in bacteria, mammals, plants, and in fungi. They are dimeric or tetrameric enzymes that bind two atoms of zinc per subunit [1]. A number of other zinc-dependent dehydrogenases are closely related to zinc ADH such as sorbitol dehydrogenase, L-threonine 3-dehydrogenase, glutathione-dependent formaldehyde dehydrogenase, mannitol dehydrogenase, and NADP-dependent quinone oxidoreductase.

Allergens from this family

The allergen Cand a 1 from Candida albicans is an alcohol dehydrogenase [2].
