A Customizable Approach for the Enzymatic Production and Purification of Diterpenoid Natural Products

DOI: 10.3791/59992-v
What you'll learn
  • ✓ Design and execute combinatorial enzyme co-expression in E. coli or N. benthamiana for diterpenoid synthesis
  • ✓ Perform culture preparation, induction, and metabolite extraction workflows
  • ✓ Apply chromatographic purification to isolate and characterize diterpenoid products
Protocol

Biopharma Insights Here we present easy to use protocols for producing and purifying diterpenoid metabolites through the combinatorial expression of biosynthetic enzymes in Escherichia coli or Nicotiana benthamiana, followed by chromatographic product purification. The resulting metabolites are suitable for various studies including molecular structure characterization, enzyme functional studies, and bioactivity assays.

Steps

1
Express diterpenoid biosynthetic enzymes in E. coli

Clone and express selected biosynthetic genes in E. coli for combinatorial diterpenoid production. This foundational step establishes enzyme co-expression systems tailored to target metabolites.

2
Prepare inoculation culture starter

Inoculate overnight starter cultures from selected clones or colonies to generate sufficient biomass for induction experiments.

▶ 02:14
3
Induce co-expression in main cultures

Scale inoculation cultures into larger volumes, apply induction conditions (typically IPTG or auto-induction), and grow cells to accumulate expressed enzymes and diterpenoid products.

4
Extract and purify diterpenoid metabolites

Harvest cells, perform solvent extraction, and apply chromatographic techniques (e.g., column or HPLC) to isolate and purify target diterpenoid compounds.

5
Validate and characterize purified products

Analyze enzymatic production yields and purification efficiency using representative diterpenoid samples, confirming product identity and suitability for downstream studies.
