Its use and gene coding for a protein having the diacetyl reduction activity or vicinal diketone

摘要

Relates to a use and a gene encoding a protein having the diacetyl reduction activity or vicinal diketones, in particular, brewing yeast for producing alcoholic beverages with superior flavor, alcoholic beverages were produced using the yeast, the invention relates to such a method of manufacturing the same. Specifically, genes MMF1 that encodes Mmf1p is a protein having a diacetyl reduction activity or vicinal diketone of brewing yeast, the present invention is, by increasing the expression level of ScMMF1 gene or nonScMMF1 genes characteristic of brewer's yeast and more particularly yeast with improved flavor of the product, and related method for producing an alcoholic beverage using the yeast.
