Regions associated with the stable maintenance of plasmid pSC101 and its tetracycline resistance
Abstract
Two regions tentatively called unsA and unsR were identified on pSC101. One, unsA, corresponds to less than 650 bp of the N-terminal in the tetracycline resistance structural gene and seems to inhibit stable maintenance of pSC101. The other, unsR, is defined within the 1 kb XhoI-EcoRI region located upstream of the tetracycline resistance structural gene and is a regulatory gene clearly distinct from tetR (Unger et al. 1984); it serves as a suppressor of the unsA function.
