Solution Overview
Problem
Existing graphical display systems for biosynthesis pathways fail to accurately calculate and display suitable heterologous biosynthesis pathways for a specified host organism, as they do not adequately consider the endogenous metabolism and competing reactions, leading to inaccurate design decisions in heterologous biosynthesis systems.
Innovation Solution
The Metabolic Route Explorer (MRE) system dynamically searches, analyzes, and displays ranked biosynthesis pathways by considering competing endogenous reactions and suggesting foreign enzymes that are well-characterized and suitable for the host organism's metabolic infrastructure, using thermodynamic data to rank pathways and provide insights for optimizing heterologous pathways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If prior art graphical display systems are used to display biosynthesis pathways, then the system provides basic pathway display functionality, but the accuracy of pathway determination is insufficient because host parameters and endogenous metabolism are not adequately considered
Solution Approach 1:
The system segments the pathway determination process into distinct analytical components: (1) pathway generation from source to target compound, (2) host parameter analysis, (3) endogenous metabolism assessment, and (4) pathway scoring/ranking. This segmentation allows each component to be processed independently with appropriate algorithms, improving accuracy without overwhelming system complexity.
Solution Approach 2:
The system performs preliminary analysis of host parameters and endogenous metabolism before final pathway determination. By pre-processing host organism characteristics and existing metabolic pathways, the system prepares reference data that accelerates the main pathway determination process and ensures accurate host-specific pathway recommendations.
2Measurement precision
If comprehensive host parameter analysis is performed to accurately determine suitable biosynthesis pathways, then the accuracy of pathway determination is improved, but the computation time increases
Solution Approach 1:
The system performs preliminary analysis of host parameters and endogenous metabolism before final pathway determination. By pre-processing host organism characteristics and existing metabolic pathways, the system prepares reference data that accelerates the main pathway determination process and ensures accurate host-specific pathway recommendations.
Solution Approach 2:
The system automatically retrieves and processes host parameter data from databases without requiring manual input. The system self-services by autonomously gathering host organism information, analyzing endogenous pathways, and integrating this data into the pathway determination process, reducing both computation time and user effort.
3Reliability
If the system considers competing endogenous reactions and host-specific factors, then the suitability of recommended pathways for the host organism is improved, but the complexity of the analysis increases
Solution Approach 1:
The system segments the pathway determination process into distinct analytical components: (1) pathway generation from source to target compound, (2) host parameter analysis, (3) endogenous metabolism assessment, and (4) pathway scoring/ranking. This segmentation allows each component to be processed independently with appropriate algorithms, improving accuracy without overwhelming system complexity.
Solution Approach 2:
The system introduces an intermediary scoring mechanism that mediates between pathway characteristics and host parameters. The pathway score integrates multiple factors including thermodynamic feasibility, enzyme availability, and compatibility with host endogenous metabolism. This intermediary scoring system simplifies the complex multi-parameter analysis into a single ranked output that reflects overall pathway suitability.
4Loss of information
If the system provides detailed analysis of chemical transformations and thermodynamic considerations, then the information quality for pathway design is improved, but the ease of operation decreases
Solution Approach 1:
The system introduces an intermediary scoring mechanism that mediates between pathway characteristics and host parameters. The pathway score integrates multiple factors including thermodynamic feasibility, enzyme availability, and compatibility with host endogenous metabolism. This intermediary scoring system simplifies the complex multi-parameter analysis into a single ranked output that reflects overall pathway suitability.
Solution Approach 2:
The system provides multiple levels of information presentation to serve different user needs. The same core analysis engine generates both detailed technical data (for experts) and simplified ranked summaries (for general users). The graphical user interface adapts to display appropriate detail levels, making the system universally useful across different expertise levels while maintaining comprehensive analytical capabilities.
