Discovering A Novel Antifungal Target In Downstream Sterol Biosynthesis Using A Squalene Synthase Functional Motif, Kristin Brooke Linscott

Theses and Dissertations--Molecular and Cellular Biochemistry

The sterol biosynthetic pathway is essential for growth of all eukaryotic cells and the main target of antifungal agents. The emergence of resistance to these antifungals in an already ill patient population indicates a need to develop drugs that have a broad spectrum of activity among pathogenic fungi and have minimal patient toxicity. Squalene synthase is the first committed step in the sterol pathway and has been studied intensively for development of antifungal agents. While the overall architecture of this enzyme is identical throughout eukaryotes, it was shown that plant and animal genes cannot complement a squalene synthase knockout mutation …
