Bacterial terpene biosynthesis: challenges and opportunities for pathway engineering.

Area of Science:

• Natural Product Biosynthesis
• Synthetic Biology
• Metabolic Engineering

Background:

• Terpenoids represent the largest and most structurally varied class of natural products, exhibiting potent bioactivity against diseases like cancer and malaria.
• Despite extensive characterization of terpenoid molecules, their biosynthetic pathways remain poorly understood, especially in bacteria, limiting the association of genetic potential with molecular structures.
• The canonical terpene pathway involves a single enzyme for backbone formation followed by extensive tailoring, leading to diverse products from a single precursor.

Purpose of the Study:

• To explore the potential of synthetic biology for engineering terpenoid biosynthesis.
• To deepen the understanding of bacterial terpenoid biosynthetic pathways.
• To facilitate the rational design and production of valuable terpenoids.

Main Methods:

• Leveraging synthetic biology tools for pathway engineering.
• Investigating bacterial genetic potential for terpenoid synthesis.
• Analyzing the functional promiscuity of terpene biosynthetic enzymes.

Main Results:

• Demonstrated that terpene biosynthetic pathways are amenable to rational engineering.
• Identified bacterial genetic potential for complex terpenoid biosynthesis.
• Established a foundation for creating known and novel terpenoids through engineered pathways.

Conclusions:

• Engineered terpenoid pathways enhance understanding of this significant biosynthetic branch.
• Insights gained empower greater engineering proficiency for non-natural pathways.
• Paved the way for the biotechnological production of high-value terpenoids.
