Stereochemical disposition of the geminal dimethyl groups in the enzymatic cyclization of geranyl diphosphate to (+)-bornyl diphosphate by recombinant (+)-bornyl diphosphate synthase from Salvia officinalis
摘要:
Regiospecifically deuterated geranyl diphosphate, in concert with NMR spectrometry, was employed to demonstrate that the trans-methyl group (C8) of geranyl diphosphate becomes the C9 carbon of (+)-bornyl diphosphate (geminal methyl syn to the diphosphate moiety) and that the cis-methyl group (C9) becomes the C8 (geminal methyl anti to the diphosphate). The syntheses of the relevant substrates and products, with accompanying spectrometric data are provided. (C) 2001 Elsevier Science Ltd. All rights reserved.

This invention relates to a transgenic bryophytic cell capable of producing geranyl pyrophosphate (GPP), farnesyl-pyrophosphate (FPP) and/or geranylgeranyl pyrophosphate (GGPP) comprising at least one heterologous nucleic acid molecule encoding at least one chimeric protein comprising at least a first and a second polypeptide where said first and second polypeptides are operationally linked and said first polypeptide is a lipid body-associated protein.The invention further relates to a method for producing the transgenic bryophytic cell as well as a method for preparing terpenes and terpenoids using the transgenic bryophytic cells.
