Studies on the reversion characteristics of Escherichia coli strains carrying various mutations in the pts region have led to the recognition of a mutation, suc-1, with a previously undescribed phenotype. Strains carrying the suc-1 mutation grow normally on most sources of carbon but are unable to utilize succinate effectively. The suc-1 mutation can be separated genetically from the tightly linked ptsI6 mutation. Reversion of suc-1 mutants for growth on succinate yields interesting classes of suppressor mutations.
糖磷酸转移酶系统(pts)区域携带各种突变的大肠杆菌菌株的回复突变特性研究,已导致识别出一种具有先前未描述表型的突变,即suc-1。携带suc-1突变的菌株在大多数碳源上能正常生长,但不能有效利用琥珀酸盐。suc-1突变可通过遗传学方法与紧密连锁的ptsI6突变分离。suc-1突变体在琥珀酸盐上生长的回复突变产生了有趣的抑制突变类别。
