P. Mcnicholas et al., GENETIC-ANALYSIS SUGGESTS FUNCTIONAL INTERACTIONS BETWEEN THE N-TERMINAL AND C-TERMINAL DOMAINS OF THE TETA(C) EFFLUX PUMP ENCODED BY PBR322, Journal of bacteriology, 177(18), 1995, pp. 5355-5357
Genetic analysis of the tetA(C) gene of pBR322 indicates the importanc
e of two cytoplasmic loops in the TetA(C) protein (P. McNicholas, I. C
hopra, and D. M. Rothstein, J. Bacteriol. 174:7926-7933, 1992). In thi
s study, we characterized Second-site suppressor mutations that sugges
t a functional interaction between these two cytoplasmic regions of th
e protein.
