A method involving a circular expression vector with specific restriction sites for type II S restriction enzymes, allowing for digestion and circular ligation to create multimeric protein or peptide structures, enabling the assembly of sequences that cannot be precisely cloned conventionally, and allowing for automated and high-yield production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional cloning techniques are used to assemble multimeric protein structures, then the process is simple and familiar, but the ability to produce long sequences and tailored multimeric structures is limited
Solution Approach 1:
The invention segments the assembly process into modular steps: (1) preparing individual protein or peptide sequences with defined properties, (2) assembling them into multimeric structures using controlled ligation, and (3) optionally degrading back to monomers. This segmentation enables precise control over the assembly of long sequences and complex multimeric structures that cannot be achieved with conventional cloning, directly resolving the contradiction between assembly precision and adaptability.
Solution Approach 2:
The invention introduces dynamic control through the optional degradation step, where assembled multimeric structures can be selectively broken down into monomeric units. This dynamic reversibility allows the system to adapt between different structural states (assembled vs. disassembled), enabling versatile production of tailored structures while maintaining precision through controlled assembly and disassembly cycles.
2Productivity
If automated high-yield production methods are implemented, then productivity increases, but process complexity increases
Solution Approach 1:
The invention employs self-service mechanisms where the system uses its own components (restriction enzymes, ligases, and defined sequences) to automatically assemble multimeric structures without requiring complex external intervention. The controlled ligation process and optional degradation create a self-regulating system that achieves high yields through automated biochemical reactions, resolving the contradiction between productivity and process complexity.
