This part is a mutant of a gene encoding ChlR, a resistance protein of chloramphenicol, and it is nonsense mutated at its 92nd amino acid residual. We used this mutated ChlR as one of the targets of our directed evolution process. After expression in BL21(DE3), we counted the number of colonies grown on a medium plate containing chloramphenicol to show its inability of being resistant to chloramphenicol.

Chloramphenicol Resistance Gene Y92X (ChlR_Y92X)

This part is a mutant of a gene encoding ChlR, a resistance protein of chloramphenicol, and it is nonsense mutated at its 92nd amino acid residual. We used this mutated ChlR as one of the targets of our directed evolution process. After expression in BL21(DE3), we counted the number of colonies grown on a medium plate containing chloramphenicol to show its inability of being resistant to chloramphenicol.
