Novel substrates of yeast alcohol dehydrogenase-3. 4-dimethylamino-cinnamaldehyde and chloroacetaldehyde.

4-Dimethylamino-trans-cinnamaldehyde and chloroacetaldehyde are novel substrates of yeast alcohol dehydrogenase (EC 1.1.1.1). In the present work, we have reported the steady-state kinetic constants for both substrates, and their chemical reactions with the enzyme protein itself. Both substrates are potentially useful for biotechnology, chemoenzyme syntheses and analytical biochemistry.
