Investigation And Engineering Of Polyketide Biosynthetic Pathways, Lei Sun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research is focused on investigation and engineering of natural product biosynthetic pathways for efficient production of pharmaceutically important molecules or generation of new bioactive molecules for drug development.

Natural products are an important source of therapeutics, such as chromomycin (anti-cancer), emodin (anti-inflammatory and anti-tumor) and sprolaxine (anti-Helicobacter pylori). Metabolic engineering of natural product biosynthetic pathways shows its promise for creating and producing valuable compounds with chemical diversity for drug discovery. One goal of this research is to create highly efficient strains to biosynthesize valuable natural products. The engineered Streptomyces roseiscleroticus strain constructed in this work showed higher …
