Directed evolution of aminoglycoside phosphotransferase (3') type IIIa variants that inactivate amikacin but impose significant fitness costs.

The rules that govern adaptive protein evolution remain incompletely understood. Aminoglycoside aminotransferase (3') type IIIa (hereafter abbreviated APH(3')-IIIa) is a good model enzyme because it inactivates kanamycin efficiently; it recognizes other aminoglycoside antibiotics, includin...
