  • Title: Isolation, purification, and study of certain properties of diacetyl(acetoin) reductase in the yeast Saccharomyces vini.
    Author: Kavadze AV, Rodopulo AK, Shaposhnikov GL.
    Journal: Biol Bull Acad Sci USSR; 1979; 6(3):356-61. PubMed ID: 45079.
    Abstract:
    A highly active preparation of diacetyl(acetoin) reductase was isolated from cell-free extracts of the yeast Saccharomyces vini. Since the activity ratio of 2,3-butanediol dehydrogenase and diacetyl(acetoin) reductase was practically unchanged in the process of 65-fold purification, it can be assumed that the yeast cells contain one enzyme, which catalyzes both the reversible oxidation of 2,3-butanediol to acetoin by NAD and the practically irreversible reduction of diacetyl to acetoin by NAD-H2. Some properties of this enzyme were studied.
