Abstract
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.
