Identification of 9,17-dioxo-1,2,3,4,10,19-hexanorandrostan-5-oic acid, 4-hydroxy-2-oxohexanoic acid, and 2-hydroxyhexa-2,4-dienoic acid and related enzymes involved in testosterone degradation in Comamonas testosteroni TA441.
Also acts, more slowly, on glycolaldehyde, propanal and butanal. In several bacterial species this enzyme forms a bifunctional complex with EC 18.104.22.168, 4-hydroxy-2-oxovalerate aldolase. The enzymes from the bacteria Burkholderia xenovorans and Thermus thermophilus also perform the reaction of EC 22.214.171.124, 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 .
EC 126.96.36.199 created 1961, modified 2006, modified 2011
