Investigation of the stereochemistry of the hydride transfer in reactions catalyzed by the recently isolated NAD⁺-linked alcohol dehydrogenase from the Antarctic psychrophile Moraxella sp. TAE123 was accomplished by using ¹H NMR spectroscopy of the deuterated coenzyme. It was found that this new psychrophilic enzyme is a type A dehydrogenase. Moraxella sp. ADH reduces stereospecifically 2-butanone to produce (S)-2-butanol.
