补充资料:调节突变株
分子式:
CAS号:

性质: 因操纵子的调节基因或操纵基因发生突变而使结构基因所编码的酶的合成调节方式发生改变的突变类型。以大肠杆菌为例:当乳糖操纵子的调节基因发生i-突变,则阻遏物失去活性,β-半乳糖苷酶等的合成从诱导型变为组成型,若发生is突变,则阻遏物不能与诱导物相结合而始终结合在操纵基因上,酶的合成变为超阻遏型;如果操纵基因发生突变,酶的合成变为组成型。当色氨酸操纵子的调节基因发生突变,是阻遏物蛋白失去活性,即使存在色氨酸也不能与它结合成为完全阻遏物,因此无法结合到操纵基因上,酶的合成不受色氨酸阻遏;如果操纵基因发生突变,酶合成也不受色氨酸阻遏。阿拉伯糖操纵与调节基因C所编码的蛋白质与诱导物结合时具有激活作用,而不与诱导物结合时具有阻遏作用。当发生C突变,则其产物不需与诱导物结合便成为激活蛋白,酶合成由诱导型变为组成型,若发生C-缺失突变,则酶合成变为超阻遏型。调节突变株在代谢调节的研究和育种中有广泛的应用。
