Background:

6-(γ,γ-Dimethylallylamino)purine is a plant growth substance.

Derivative UV spectroscopic data show that the plant growth substances 6-(γ,γ-Dimethylallylamino)purine (N6-(delta 2-isopentenyl) adenine, i6Ade)and indolylacetic acid (IAA) can bind to the yeast alcohol dehydrogenase (ADH) and affect coenzyme-enzyme binding. At fixed ethanol concentrations (27.8 and 111.1 mM) and varying NAD+ concentrations (0.033-2 mM), as well as at fixed levels of coenzyme (0.67 and 2 mM), and at varying concentrations of ethanol (1.4-111.1 mM), the rate of ethanol oxidation is significantly inhibited by i6Ade and IAA. The kinetics of the ADH reaction is affected by two inhibition constants (Ki and Ki’) which correspond to the dissociation constants of complexes EI and ESI, respectively. For i6Ade the Ki=0.52±0.06 mM and Ki’=0.74±0.07 mM, and for IAA the Ki=0.88±0.03 mM and Ki’=0.99±0.02 mM[1].
