Rim15p of the yeast is a Greatwall-family protein kinase that inhibits alcoholic fermentation during sake brewing. To elucidate the roles of Rim15p in barley shochu fermentation, was deleted in shochu yeast. The disruptant did not improve ethanol yield, but altered sugar and glycerol contents in the mash, suggesting that Rim15p has a novel function in carbon utilization.
酵母的Rim15p是一种Greatwall家族蛋白激酶,在清酒酿造过程中抑制酒精发酵。为了阐明Rim15p在大麦烧酒发酵中的作用,在烧酒酵母中删除了该基因。突变体并没有提高乙醇产量,但改变了醪液中的糖和甘油含量,这表明Rim15p在碳利用方面具有新功能。
