CLASS 3 ALDEHYDE DEHYDROGENASE COMPLEX WITH NICOTINAMIDE-ADENINE-DINUCLEOTIDE
OverviewOverview
The first structure of an aldehyde dehydrogenase (ALDH) is described at, 2.6 A resolution. Each subunit of the dimeric enzyme contains an, NAD-binding domain, a catalytic domain and a bridging domain. At the, interface of these domains is a 15 A long funnel-shaped passage with a 6 x, 12 A opening leading to a putative catalytic pocket. A new mode of NAD, binding, which differs substantially from the classic beta-alpha-beta, binding mode associated with the 'Rossmann fold', is observed which we, term the beta-alpha,beta mode. Sequence comparisons of the class 3 ALDH, with other ALDHs indicate a similar polypeptide fold, novel NAD-binding, mode and catalytic site for this family. A mechanism for enzymatic, specificity and activity is postulated.
