The effect of ammonium on glutamine synthetase of fodder yeast Candida tropicalis was studied. Ammonium ions were found to repress the synthesis of glutamine synthetase of fodder yeast and to inhibit the enzyme in the cells. The substitution of glutamic acid for ammonium in the nutrient medium brought about depression of glutamine synthetase.
研究了铵对饲料酵母热带假丝酵母谷氨酰胺合成酶的影响。发现铵离子会抑制饲料酵母谷氨酰胺合成酶的合成,并抑制细胞中的该酶。在营养培养基中用谷氨酸替代铵会导致谷氨酰胺合成酶活性降低。
