EnzyDiscover AI: Intelligent Platform for Enzyme Discovery and Engineering

1. Overview

EnzyDiscover AI is a next-generation platform that integrates artificial intelligence, public biological databases, and advanced computational methods to accelerate enzyme discovery and engineering. The platform will allow researchers, biotech companies, and academia to identify novel enzymes, predict catalytic activity, optimize stability, and design variants for industrial, pharmaceutical, and environmental applications. It addresses the complexity of searching across fragmented enzyme-related repositories by centralizing knowledge and augmenting it with predictive AI models.

2. Problem Statement

Current enzyme discovery and engineering pipelines are slow, resource-intensive, and fragmented. Researchers often need to search across multiple repositories such as UniProt, BRENDA, KEGG, and PDB, then manually cross-reference activity data, sequences, and structural information. Moreover, computational tools are not easily integrated, requiring different expertise for bioinformatics, molecular modeling, and protein engineering. This fragmentation results in high costs and delays in developing enzymes for biocatalysis, green chemistry, and therapeutic applications.

3. Objectives

  1. Build a unified search and knowledge platform for enzyme-related data.
  2. Apply AI models to predict enzyme activity, substrate specificity, and stability.
  3. Integrate structural modeling (AlphaFold/PDB) for visualization and rational design.
  4. Enable automated variant suggestion for enzyme optimization.
  5. Provide exportable workflows for industry and academia, including regulatory documentation.

4. Research Questions

  • Can AI-driven sequence–function prediction achieve >80% accuracy compared to curated enzymology datasets?
  • Do structural AI models (AlphaFold2/ESMFold) combined with molecular dynamics simulations reduce the time required for variant assessment by 50%?
  • Can enzyme-substrate interaction predictions improve success rates of biocatalyst design for industrial reactions?
  • Will researchers perceive higher trust when AI outputs are coupled with cited evidence from repositories (e.g., BRENDA, KEGG)?

5. Methodology

  • Data Integration: Ingest enzyme sequences (UniProt), catalytic activity and kinetics (BRENDA), metabolic pathways (KEGG), protein structures (PDB/AlphaFold), and patents.
  • ETL Pipelines: Normalize identifiers (EC numbers, UniProt IDs, KEGG pathways).
  • Machine Learning Models: Train predictive models (transformer-based) for sequence-to-function mapping, substrate binding, thermostability, and solubility.
  • Molecular Modeling: Integrate docking simulations (AutoDock, Rosetta) and molecular dynamics for variant validation.
  • Knowledge Graph: Connect enzymes to substrates, pathways, diseases, and industrial processes.
  • Web Portal: Conversational and dashboard interfaces with visualizations, workflows, and export options.

6. Technical Approach

  • Backend: Python (FastAPI) for APIs, orchestrating ML pipelines.
  • Databases: PostgreSQL for metadata, Neo4j for knowledge graph, Qdrant/Milvus for embeddings.
  • AI Models: Sequence embeddings (ESM, ProtBERT), structural models (AlphaFold2, Rosetta).
  • Frontend: React + Cytoscape.js for enzyme-substrate networks, PyMOL integration for 3D views.
  • Infra: GCP/Azure for scalability; GPU-enabled nodes for ML training and molecular modeling.

7. Expected Outcomes

  • A unified platform for enzyme discovery and engineering.
  • AI-assisted predictions of enzyme activity and stability.
  • Automated enzyme variant recommendations for improved efficiency.
  • Visualization of enzyme–substrate networks and metabolic pathways.
  • Exportable workflows (PDF, CSV, SBML) for academic and industrial use.

8. Innovation

Unlike traditional enzyme databases, EnzyDiscover AI combines AI-driven predictions with knowledge graph exploration, enabling discovery of hidden relationships between enzymes, substrates, and pathways. Its integration of predictive ML, structural biology, and interactive visualization makes it a disruptive tool for enzyme R&D.
