Evolution of biosynthetic pathways: immunological approach.

Directed evolution of enzymes and biosynthetic pathways.

Directed evolution is an important tool for overcoming the limitations of natural enzymes as biocatalysts. Recent advances have focused on applying directed evolution to a variety of enzymes, such as epoxide hydrolase, glyphosate N-acetyltransferase, xylanase and phosphotriesterase, in order to improve their activity, selectivity, stability and solubility. The focus has also shifted to manipula...

Reviewing Colchicaceae Alkaloids – Perspectives of Evolution on Medicinal Chemistry

The subject of chemosystematics has provided insight to both botanical classification and drug development. However, degrees of subjectivity in botanical classifications and limited understanding of the evolution of chemical characters and their biosynthetic pathways has often hampered such studies. In this review an approach of taking phylogenetic classification into account in evaluating colc...

A MATHEMATICAL MODEL TO DESCRIBE THE SYNERGISTIC EFFECT BETWEEN SULFAMETHOXAZOLE AND TRIMETHOPRIM

b a s e don folic acid biosynthetic pathway a mathematical model was made for bacterial growth to describe the synergistic effect between sulfamethoxazole and trimethoprim. The results obtained show a strong synergism at growth inhibiting concentrations of these two drugs. Two cyclic pathways included in the model are responsible for this synergism. The roles of these pathways in producing ...

In silico identification of miRNAs and their target genes and analysis of gene co-expression network in saffron (Crocus sativus L.) stigma

As an aromatic and colorful plant of substantive taste, saffron (Crocus sativus L.) owes such properties of matter to growing class of the secondary metabolites derived from the carotenoids, apocarotenoids. Regarding the critical role of microRNAs in secondary metabolic synthesis and the limited number of identified miRNAs in C. sativus, on the other hand, one may see the point how the characte...
