Hypothetical structure of the QnrE. faecalis protein. The amino acid sequence of QnrE. faecalis was divided into pentapeptide repeats organized in two domains of 9 and 33 units each and connected by a single asparagine. The conserved amino acid residues according to the consensus sequence (A/C) (D/N) (L/F) (S/R) (G/R) are in bold, and the most characteristic pentapeptide units are underlined.
