This study introduces a machine learning workflow to predict the substrate scope of fungal Type III polyketide synthases (T3PKSs). This tool aids in biocatalysis and understanding enzyme function.
Area of Science:
- Biochemistry
- Computational Biology
- Enzymology
Background:
- Type III polyketide synthases (T3PKSs) are crucial enzymes producing diverse natural products.
- Their substrate promiscuity contributes to a broad product scope, important for ecological and clinical applications.
- Predicting T3PKS substrate scope is key for biocatalysis and understanding biological roles.
Purpose of the Study:
- To present a machine learning-based workflow for predicting substrate specificity in fungal T3PKSs.
- To provide protocols for predicting T3PKS substrate scope and selecting enzymes for specific transformations.
- To offer guidance on retraining the model with custom enzymatic activity data.
Main Methods:
- Development of a machine learning workflow tailored for fungal T3PKSs.
- Implementation of step-by-step protocols for substrate scope prediction.
- Inclusion of instructions for model retraining and figure generation.
Main Results:
- A functional machine learning workflow for predicting T3PKS substrate specificity.
- Protocols enabling prediction of new T3PKS substrate scopes.
- Guidance on selecting T3PKSs for targeted substrate transformations.
Conclusions:
- The developed workflow facilitates accurate prediction of T3PKS substrate specificity.
- This approach supports the application of T3PKSs in biocatalysis.
- The workflow aids in elucidating the biological functions of T3PKSs.
