Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metabolic engineering methods are used to optimize biosynthetic pathways, then molecules can be produced through engineered organisms, but the process becomes costly and time-consuming due to the complexity of cell membranes and extensive design-build-test cycles
Solution Approach 1:
The patent extracts the essential metabolic functions from living cells by using cell-free systems. Specifically, it isolates enzymes and metabolic pathways from their cellular context, allowing them to function in a simplified in vitro environment. This extraction eliminates the complexity of cell membranes and regulatory networks while preserving the core biosynthetic capabilities, thereby reducing the time and cost of design-build-test cycles.
Solution Approach 2:
The patent segments the metabolic pathway into discrete enzymatic steps that can be independently optimized and recombined. By dividing the biosynthetic pathway into modular enzyme components, researchers can systematically test and optimize individual steps without affecting the entire system, significantly reducing the complexity and duration of iterative engineering cycles.
2Reliability
If traditional metabolic engineering methods are used to optimize biosynthetic pathways, then molecules can be produced through engineered organisms, but the process becomes costly and time-consuming due to the complexity of cell membranes and extensive design-build-test cycles
Solution Approach 1:
The patent removes the cell membrane and associated cellular complexity by using cell-free extracts. The metabolic enzymes are extracted from cells and placed in a simplified in vitro system, eliminating the need to account for membrane transport, cellular regulation, and other complex biological factors while maintaining the essential biosynthetic functions.
Solution Approach 2:
The patent changes the physical and chemical parameters of the system by transitioning from in vivo to in vitro conditions. This parameter change simplifies the system by removing cellular constraints while allowing precise control over enzyme concentrations, substrate availability, and reaction conditions, thereby reducing overall system complexity.
3Productivity
If cell-free systems are used for metabolic engineering, then the time and cost of producing chemical and natural products is reduced by bypassing cellular constraints, but the system requires direct manipulation of metabolic processes in vitro
Solution Approach 1:
The cell-free system is designed to be self-sufficient by including all necessary components for metabolic function within the extract. The system contains enzymes, cofactors, and other essential elements needed for biosynthesis, allowing it to operate autonomously in vitro without requiring complex cellular infrastructure, thus improving productivity while maintaining ease of operation.
