    Aldehyde dehydrogenases catalyze the oxidation of aldehyde substrates to the corresponding carboxylic acids. Lactaldehyde dehydrogenase from Escherichia coli (aldA gene product, P25553) is an NAD(+)-dependent enzyme implicated in the metabolism of l-fucose and l-rhamnose. During the heterologous expression and purification of taxadiene synthase from the Pacific yew, lactaldehyde dehydrogenase from E. coli was identified as a minor (
