摘要:
The present invention provides a method of producing α-santalene by contacting at least one polypeptide with farnesyl phyrophosphate (fpp). In particular, the method may be carried out in vitro or in vivo to produce α-santalene, a very useful compound in the fields of perfumery and flavoring. The present invention also provides the amino acid sequence of a polypeptide useful in the method of the invention. A nucleic acid encoding the polypeptide of the invention and an expression vector containing the nucleic acid represent part of the present invention. A non-human host organism and a cell transformed to be used in the method of producing α-santalene are also part of the present invention.
摘要:
An isolated nucleic acid molecule encoding a 7-epizingiberene synthase, a chimeric gene comprising the nucleic acid molecule, vectors comprising the same, as well as isolated 7-epizingiberene synthase proteins themselves, are provided. In addition, transgenic plants and plant cells comprising a gene encoding a 7-epizingiberene synthase, optionally integrated in its genome, and methods for making such plants and cells, are provided. Especially Solanaceae plants and plant parts (seeds, fruit, leaves, etc.) with enhanced insect pest resistance are provided.
摘要:
Provided are modified santalene synthase polypeptides, nucleic acid molecules encoding the modified santalene synthase polypeptides, and methods of using the modified santalene synthase polypeptides. The modified santalene synthase polypeptides include those that catalyze production of increased levels of terpenes or altered profiles thereof or both.
