additional information specificity data for PpBADH shows that long chain aliphatics containing 5-8 carbons have about twice the relative rate of reactivity than benzaldehyde. As the chain length decreases, the activity declines quickly, with less than 0.1% activity being observed with acetaldehyde. Structure-function analysis Pseudomonas putida ?

General Information

General Information Comment Organism
evolution benzaldehyde dehydrogenase from Pseudomonas putida (PpBADH) belongs to the Class 3 aldehyde dehydrogenase (ALDH) family. The Class 3 ALDHs are unusual in that they are generally dimeric (rather than tetrameric), relatively non-specific and utilize both NAD+ and NADP+. The pattern of cofactor binding for the rat Class 3 ALDH differs from that of PpBADH and other ALDHs Pseudomonas putida
metabolism benzaldehyde dehydrogenase (PpBADH) is the terminal enzyme in the mandelamide/mandelate pathway of Pseudomonas putida strain ATCC 12633, it catalyzes the conversion of benzaldehyde to benzoic acid with the concomitant reduction of NAD+ (EC 1.2.1.28) or NADP+ (EC 1.2.1.7) to NADH or NADPH, respectively. Benzoic acid subsequently enters the beta-oxoadipate pathway and the citric acid cycle Pseudomonas putida
additional information two conserved glutamates, at positions 215 and 337, might act as the general base necessary to hydrolyze the thioacyl intermediate, structure-activity relationship, mechanism, overview. Glu215 is the likely candidate for PpBADH, a result more typical of the Class 1 and 2 ALDH families. Hydride transfer is not rate limiting, lending further credence to the suggestion that PpBADH is more similar to the Class 1 and 2 ALDHs than it is to other Class 3 ALDHs.
