[Methanol oxidation by the NAD-specific dehydrogenase of methane-assimilating yeasts]
Abstract
The activity of NAD-specific dehydrogenase (NAD-DH) capable of methanol oxidation was found in cell-free extracts of methanol assimilating yeast cultures Pichia pinus and Candida boidinii. The optimum pH of the incubation mixture for the enzyme is 7.8--7.9; the value of Km of the enzyme for methanol is 1.4-10(-4) M in P. pinus and 1.04-10(-3) M in C. boidinii. NAD-DH is absent from the cells cultivated on glucose, and is induced with growth on a medium containing methanol.
