Title:
分岐鎖アミノ酸アミノ基転移酵素遺伝子及びその用途
Document Type and Number:
Japanese Patent JP2008530979
Kind Code:
A
Abstract:
The present invention relates to a branched-chain amino acid aminotransferase gene and a use thereof, particularly, to a brewery yeast for producing alcoholic drinks with enhanced flavor, to alcoholic drinks produced with said yeast and to a method for producing said drinks. More particularly, the present invention relates to a yeast whose capacity of producing amyl alcohol and/or isobutanol and/or isoamyl acetate that contribute to the product flavor is controlled by controlling the expression levels of BAT1 and BAT2 genes coding for brewery yeast branched-chain amino acid aminotransferases Bat1p and Bat2p, respectively, particularly nonScBAT1 or nonScBAT2 gene specific to lager brewing yeast, and to a method for producing alcoholic drinks using said yeast.
