Based on the investigation in Longxi Mountain National Nature Reserve and the theory of survival analysis, a static life table of Taxus chinensis var. mairei population was worked out, the curves of its survival rate, mortality rate and killing power were drawn, and the population dynamics was analyzed by spectral analysis. The results showed that the survival curve of the population appeared to be a type of Deevey-III, and the high mortality of seeding was one of the important reasons which caused Taxus chinensis var. mairei to be endangered. The spectral analysis of the population showed that there was a marked periodic regularity in the process of natural regeneration of Taxus chinensis var. mairei.

Despite the discovery of numerous oncogenes in colorectal cancer (CRC), the development of associated drugs is limited, posing a significant challenge for CRC treatment. Identification of novel druggable targets is therefore crucial for the therapeutic development of CRC. Here, we report the first investigation on therapeutics targeting the potent oncogene NUCKS1 to suppress cancer progression.

Ethnopharmacological Relevance: As one of the important by-products of Taxus chinensis (Pilg.) Rehder, its fruit (TCF) has a sweet taste, which is commonly used in folklore to make health care wine reputed for enhancing immune function and promoting anti-aging effects, especially popular in the longevity villages of China for a long history. Evidences had showed that Taxus chinensis fruit contained polysaccharides, flavonoids, amino acids and terpenoids, which all were free of toxic compounds, but its medicinal value has not been fully recognized.

Improving regioselectivity of phenylalanine aminomutase from by semi-rational mutagenesis for the biocatalytic amination of cinnamates.

Front Bioeng Biotechnol

August 2024

Laboratory of Chemical Biology and State Key Laboratory of Natural Medicines, China Pharmaceutical University, Nanjing, Jiangsu, China.

Article Synopsis
  • The study focuses on the influence of substrate binding in enzyme catalysis, specifically investigating the regioselectivity of phenylalanine aminomutase (TcPAM) in transforming cinnamates.
  • Researchers modified TcPAM's binding pocket, resulting in a variant that significantly improved the production of beta-phenylalanine over alpha-phenylalanine when using specific substrates.
  • The findings highlight the relationship between aromatic and carboxylate binding, offering valuable insights into optimizing TcPAM for biocatalytic applications involving phenylalanine derivatives.
