Point Mutation or Overexpression of Aspergillus fumigatus cyp51B, Encoding Lanosterol 14α-Sterol Demethylase, Leads to Triazole Resistance.

Abstract excerpt

Aspergillus fumigatus is the most common cause of invasive fungal mold infections in immunocompromised individuals. Current antifungal treatment relies heavily on the triazole antifungals which inhibit fungal Erg11/Cyp51 activity and subsequent ergosterol biosynthesis. However, resistance, due primarily to cyp51 mutation, is rapidly increasing. A. fumigatus contains two Cyp51 isoenzymes, Cyp51A and Cyp51B....
