Investigating the biosynthesis of tambjamines: bacterial alkaloid natural products
Natural Products are molecules produced by living organisms that serve as a means of communication and competition with other organisms. The innate bioactivities of Natural Products have been leveraged for the development of many drug therapies particularly for the treatment of infectious diseases and cancers. The prodiginines and tambjamines comprise a large family of microbially produced bioactive alkaloid Natural Products. They are characterized by a common bipyrrole and subclassified as prodiginines when they contain a third pyrrole or tambjamines with an alkyl amine instead. Despite isolation of a sizeable number of tambjamine molecules from natural sources, only a very small number of these molecules have been correlated with a producing microbe and a biosynthetic gene cluster, thereby limiting our understanding of the biosynthesis of the tambjamine subclass. In this presentation, the genome-guided isolation of several tambjamines will be discussed alongside our work on the biosynthesis of these alkaloids and investigations of several enzymatic steps in the later stages of prodiginine and tambjamine production.
