TL;DR: Using deletions and insertions, two tet genes were mapped and characterized by their mutant phenotypes and it was found that the sites controlling their expression are located in the intercistronic region between tetA and tetR.

TL;DR: Reconstitution experiments with lipid by layer membrane demonstrated that ScrY formed ion‐permeable channels with properties very similar to those of general diffusion pores of enteric bacteria.

TL;DR: In this article, homologous and heterologous repressor-operator interactions among four different classes of tetracycline resistance determinants have been compared, and the results demonstrate close relationships among the four classes of Tcr determinants.

TL;DR: Sucrose‐positive derivatives of Escherichia coli K‐12 and Klebsiella pneumoniae hydrolyse intracellular sucrose 6‐phosphate by means of an invertase into d‐glucose 6‐ phosphate and free d‐fructose and show overall identity among each other and to a kinase from Vibrio alginoiyticus also involved in sucrose metabolism.
