Protein
(-)-alpha-pinene synthase, chloroplastic
Function
Involved in defensive oleoresin formation in conifers in response to insect attack or other injury. Involved in monoterpene (C10) olefins biosynthesis. Produces mainly (-)-alpha-pinene (79%) and lesser amounts of (-)-beta-pinene (4.2%), nearly racemic mixtures of camphene (2.8% (+)/2.2% (-)) and limonene (2.4% (+)/3.7% (-)), as well as small amounts of (+)-alpha-pinene (3.3%) and (+)-beta-pinene (2.4%).
Similarity
Belongs to the terpene synthase family. Tpsd subfamily.
