| Description | 7-Xylosyl-10-deacetylbaccatin III is a natural product from Taxus brevifolia. |
| Structure Identification | Biotechnology & Applied Biochemistry, 1997, 26(3):153-158.Enzymic hydrolysis of 7-xylosyltaxanes by xylosidase from Moraxella sp.[Reference: WebLink]
The production of large quantities of paclitaxel for use as an anticancer treatment has been a difficult problem because of the low concentration of the compound in yew trees (Taxus sp.) and its occurrence as part of a mixture of other taxanes. 7-Xylosyltaxanes are major components of the mixture found in the bark of the Pacific yew (Taxus brevifolia).

Bacterial diversity of Taxus rhizosphere: culture-independent and culture-dependent approaches.[Pubmed:18576948]
FEMS Microbiol Lett. 2008 Jul;284(2):204-12.
The regional variability of Taxus rhizosphere bacterial community composition and diversity was studied by comparative analysis of three large 16S rRNA gene clone libraries from the Taxus rhizosphere in different regions of China (subtropical and temperate regions). One hundred and forty-six clones were screened for three libraries. Phylogenetic analysis of 16S rRNA gene sequences demonstrated that the abundance of sequences affiliated with Gammaproteobacteria, Betaproteobacteria, and Actinobacteria was higher in the library from the T. xmedia rhizosphere of the temperate region compared with the subtropical Taxus mairei rhizosphere. On the other hand, Acidobacteria was more abundant in libraries from the subtropical Taxus mairei rhizosphere. Richness estimates and diversity indices of three libraries revealed major differences, indicating a higher richness in the Taxus rhizosphere bacterial communities of the subtropical region and considerable variability in the bacterial community composition within this region. By enrichment culture, a novel Actinobacteria strain DICP16 was isolated from the T. xmedia rhizosphere of the temperate region and was identified as Leifsonia shinshuensis sp. via 16S rRNA gene and gyrase B sequence analyses. DICP16 was able to remove the xylosyl group from 7-Xylosyl-10-deacetylbaccatin III and 7-xylosyl-10-deacetylpaclitaxel, thereby making the xylosyltaxanes available as sources of 10-deacetylbaccatin III and the anticancer drug paclitaxel. Taken together, the present studies provide, for the first time, the knowledge of the biodiversity of microorganisms populating Taxus rhizospheres.
