Comments:

Also acts, more slowly, on glycolaldehyde, propanal and butanal. In several bacterial species this enzyme forms a bifunctional complex with EC 4.1.3.39, 4-hydroxy-2-oxovalerate aldolase. The enzymes from the bacteria Burkholderia xenovorans and Thermus thermophilus also perform the reaction of EC 1.2.1.87, propanal dehydrogenase (propanoylating). Involved in the meta-cleavage pathway for the degradation of phenols, methylphenols and catechols. NADP⁺ can replace NAD⁺ but the rate of reaction is much slower [3].
