The present invention relates to ammonia transporter genes and use thereof. The invention relates in particular to a brewer's yeast which shows enhanced ammonia assimilation, alcoholic beverages produced using such yeast, and a method of producing such alcoholic beverages. More specifically, the invention relates to the MEP1 gene which codes for the ammonia transporter Mep1 in brewer's yeast, particularly to a yeast which can control the ammonia assimilation ability by controlling the level of expression of the nonScMEP1 gene or ScMEP1 gene characteristic to beer yeast and to a method of producing alcoholic beverages using such yeast.
