Fig. 1From: Four terpene synthases contribute to the generation of chemotypes in tea tree (Melaleuca alternifolia)Products of Melaleuca alternifolia terpene synthases. The enzymes were expressed in E. coli, extracted, and incubated with the substrate GPP. Terpene products were extracted with SPME and analyzed by GC-MS on a EC5-column (a) or a AT-35-column (b). The products were: 1: α-thujene, 2: α-pinene, 3: sabinene, 4: β-pinene, 5: myrcene, 6: α-phellandrene, 7: α-terpinene 8: limonene, 9: 1,8-cineole, 10: γ-terpinene, 11: (E)-sabinene hydrate, 12: terpinolene, 13: (Z)-sabinene hydrate, 14: α-terpineol, 15: geraniol (substrate artifact), 16: geranial (substrate artifact), x: silica contaminationBack to article page
