Monoterpene Synthase Structural Modeling
Objective: To identify amino acid residues that are terpene synthesis, we constructed three-dimensional models of the terpene synthase proteins.

Three-dimensional structure of the 3 terpene synthases
Superimposition of the 3D structures of alpha-pinene synthase (blue), beta-pinene synthase (red), and limonene synthase (green). We used MODELLER (1) to automate homology-based 3D structure prediction. We identified an experimentally determined 3D structure of a taxadiene synthase from Pacific Yew (PDB ID: 3P5R) as an appropriate template.
Reactive site of the three synthases
Magnesium ions are cofactors located at the reactive site.
