Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional strain engineering methods are used for Clostridia, then in vivo implementation is achieved, but the process is low-throughput and labor-intensive
Solution Approach 1:
The patent extracts the essential biological functions (transcription and translation) from intact Clostridia cells to create a cell-free protein synthesis system. By removing the cellular context while retaining the molecular machinery, the system enables high-throughput prototyping without the constraints of living cell culture, directly addressing the low-throughput and labor-intensive nature of traditional strain engineering
Solution Approach 2:
The patent creates an in vitro copy of the cellular protein synthesis process using purified components (ribosomes, tRNAs, enzymes, metabolites) extracted from Clostridia. This synthetic replica allows parallel processing of multiple genetic parts and pathways simultaneously, dramatically increasing throughput while reducing manual intervention
2Reliability
If Clostridia are cultured under anaerobic conditions, then authentic bacterial growth is achieved, but the process is time-consuming and limited by strict environmental requirements
Solution Approach 1:
The patent extracts the protein synthesis machinery from anaerobic Clostridia cells, separating the molecular functions from the anaerobic environmental requirements. This allows the extracted components to function under aerobic laboratory conditions, eliminating the time-consuming anaerobic culture process while maintaining reliable protein synthesis output
Solution Approach 2:
The patent changes the environmental parameters from strict anaerobic conditions to aerobic conditions by using a cell-free system. The extracted enzymatic machinery operates with oxygen present, allowing standard aerobic laboratory practices to be used, thereby reducing culture time and environmental control complexity while maintaining functional reliability
3Productivity
If cell-free protein synthesis is performed using Clostridia extracts, then high-throughput prototyping is enabled, but the system complexity increases
Solution Approach 1:
The patent segments the complex cellular protein synthesis system into discrete, purified functional components (ribosomes, tRNAs, RNA polymerases, metabolites, enzymes). This segmentation allows each component to be independently characterized and optimized, simplifying the overall system architecture while enabling high-throughput screening of genetic parts and pathways
