Tobacco (Nicotianum tabacum L.) plants engineered to express a sugar beet (Beta vulgaris L.) betaine aldehyde dehydrogenase (BADH) cDNA acquired not only BADH activity, but also three other aldehyde dehydrogenase activities (those measured with 3-dimethylsulfoniopropionaldehyde, 3-aminopropionaldehyde, and 4-aminobutyraldehyde, all of which are natural products). This shows that BADH is not, as believed up to now, a substrate-specific enzyme and that its role may not be limited to glycine betaine synthesis.
