Mutations in the yeast fructose 1,6 biphosphatase structural gene severely reduced expression of a fructose 1,6 biphosphatase-endoglucanase A hybrid protein introduced into yeast on multicopy or centromeric vectors. Upon glucose limitation the mutant yeasts were incapable of de-repressing endoglucanase A synthesis.
酵母果糖1,6 -二磷酸酶结构基因的突变严重降低了通过多拷贝或着丝粒载体导入酵母中的果糖1,6 -二磷酸酶-内切葡聚糖酶A融合蛋白的表达。在葡萄糖受限的情况下,突变酵母无法解除对内切葡聚糖酶A合成的抑制。
