Solution Overview
Problem
Purifying individual cannabinoid compounds from C. sativa is time-consuming and costly, making it difficult to produce cannabinoids in large quantities and high purity for therapeutic use.
Innovation Solution
Engineering flavin-dependent oxidases with specific amino acid variations that can catalyze the oxidative cyclization of prenylated aromatic compounds into cannabinoids, such as CBGA, without disulfide bonds, and optimizing them for pH stability and cofactor binding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cannabinoids are purified from C. sativa, then high purity cannabinoid compounds are obtained, but the process is time-consuming and costly
Solution Approach 1:
The patent segments the cannabinoid production process by dividing it into two distinct parts: (1) engineered cells that produce high purity individual cannabinoid compounds through genetic modification, and (2) traditional plant extraction for obtaining mixtures. This segmentation allows selection of the appropriate method based on whether high purity or cost-effectiveness is the priority
Solution Approach 2:
The patent introduces engineered cells as an intermediary system between traditional plant cultivation and final cannabinoid product. These genetically modified cells act as biological factories that convert plant precursors into high purity cannabinoids, eliminating the need for time-consuming purification steps while maintaining high product quality
2Productivity
If cannabinoids are produced through engineered cells, then production efficiency and purity are improved, but the complexity of the production system increases
Solution Approach 1:
The engineered cells are designed to autonomously perform the cannabinoid synthesis process. The genetic modifications enable the cells to self-regulate the biochemical pathways, automatically converting precursor molecules into high purity cannabinoids without requiring complex external purification equipment or multiple processing steps
Solution Approach 2:
The patent changes the fundamental parameter of production location from plant-based extraction to cell-based synthesis. By transferring the production capability to engineered cells with modified metabolic pathways, the system achieves high productivity and purity while simplifying the overall production architecture, as cell cultures require fewer downstream processing steps compared to plant extraction
