Decreased function of the class B tetracycline efflux protein Tet with mutations at aspartate 15, a putative intramembrane residue.

Journal of bacteriology - 1 Oct 1992

McMurry L M, Stephan M, Levy S B

Abstract excerpt

The aspartate 15 residue within the first predicted intramembrane helix of the tetracycline efflux protein Tet has been conserved in four tetracycline resistance determinants from gram-negative bacteria. Its replacement in class B Tet by tyrosine, histidine, or asparagine resulted in a 60 to 85% loss of tetracycline resistance and a similar loss of tetracycline-proton antiport. The tyrosine and histidine...
