Representative Achievements

(1)Development of Knowledgebases and Models for Industrial Organisms: We created comprehensive knowledgebases for model organisms, including E. coli and C. glutamicum, by aggregating data from various databases and literature sources and integrating it with analytical tools. Through standardized network reconstruction and quality control processes, we reconstructed genome-scale metabolic models for multiple organisms. Additionally, we developed a framework for building multi-constraint models (MCMs) by incorporating enzyme and thermodynamic constraints, successfully applying this approach to construct high-quality MCMs for several industrial organisms.

(2)Design of metabolic pathways and metabolic engineering strategies: We developed web tools, including CAVE and QHEPath, to calculate and visualize optimal metabolic pathways and heterologous pathways. We designed and constructed several nonnatural C1 utilization pathways through a novel CombFBA algorithm. New tools for high throughput editing sequence design and optimization of gene operation schedules are developed, facilitating the seamless integration of computation design and experimental construction of strains in the Biofoundry platform.

(3)Enzyme Function Prediction, Mining, and Design via AI and Structural Analysis: We developed an AI-based approach to accurately predict the EC number and subunit composition of proteins. By combining multiple methods for assessing reaction similarity and quantitatively predicting enzyme parameters, we created a web tool named REME, which enables the efficient mining and screening of enzyme candidates for non-natural reactions. Additionally, we established several workflows for optimizing protein stability, activity, and selectivity through detailed structural analysis, successfully applying these methods in the design of numerous enzymes and biosensors.
