Additional information
Amy Fraley was born in Pennsylvania where she studied Chemistry at Millersville University of Pennsylvania and earned her BSc in 2014. She then earned her PhD in Medicinal Chemistry in 2019 from the University of Michigan College of Pharmacy working in the laboratories of Prof. David Sherman and Prof. Janet Smith. There, she characterized the structures enzymes involved in fungal indole alkaloid biosynthesis. These compounds contain a characteristic bicyclo[2.2.2]diazaoctane ring which is formed by a Diels-Alderase enzyme. During her graduate work, Amy discovered a new family of zinc-binding flavin-dependent halogenases that catalyze late-stage chlorination and brominaton of indole alkaloids. Subsequent structure-based engineering resulted in a suite of regioselective halogenation biocatalysts. Her interest in flavoenzyme biochemistry led to a second discovery of a flavin-dependent monooxygenase family responsible for the selective formation of spirooxindole centers. By combining the biocatalytic potential of these flavoenzymes, she generated a library of natural and new-to-nature indole alkaloids that were ultimately used to probe protein-protein interactions implicated in cardiovascular disease mechanisms.
She then moved to the ETH Zürich Institute of Microbiology for postdoctoral studies in the laboratory of Prof. Jörn Piel, with a focus on the biosynthesis of anticancer polyketides by marine symbiotic bacteria. Following biochemical investigations into one of the most versatile biochemical assembly lines characterized to-date, she pursued the cryptic formation of a cis-double bond in the sponge-associated anticancer molecule peloruside. She discovered that the biosynthetic pathway includes a novel mechanism for incorporation and maintenance of this moiety, and utlimately defined the catalytic amino acids responsible for this new transformation.
In January 2024, she became the Assistant Professor of Medicinal Chemistry in the Institute of Pharmaceutical Sciences and the Department of Chemistry and Applied Biosciences at ETH Zürich.
