Integrating structure-based machine learning and co-evolution to investigate specificity in plant sesquiterpene synthases
Fig 2
Characterized STSs visualized using the feature values of the cation-specific residues followed by dimensionality reduction using UMAP [23], which positions STSs with similar feature values closer to each other.
Squares represent farnesyl cation-specific STSs and diamonds represent nerolidyl cation-specific STSs. Each STS is also colored by its cyclization specificity. Enzymes catalyzing products from different precursor cations are marked as triangles.
