Biosynthesis of Secondary Metabolites

1993
The study of biosynthesis of secondary metabolites consists of the identification of the sequence of reactions by which the cell converts one or more primary metabolites into the final molecule. It also concerns the identification of the factors by which this process is regulated.

Engineering of secondary metabolite pathways

Current Opinion in Biotechnology, 2003
Nature produces an astonishing wealth of secondary metabolites with important biological functions. To access this diversity of structurally complex chemical compounds for industrial and biomedical applications, cells have been engineered to produce higher levels and/or novel compounds that were previously inaccessible. Recent examples of metabolic and

Chemistry of the Secondary Metabolites of Termites

2019
Isolation, structure determination, synthesis, and biochemistry of the low-molecular-weight compounds of the secretion of exocrine glands of termites are described, with an emphasis on pheromones and defensive compounds.

The physiology and biosynthesis of secondary metabolites

Acta Biologica Hungarica, 1997
Recently, several excellent reviews appeared /9, 12, 15, 29/ summarizing new findings of the last years and describing the topic in the new interconnections. The signalling systems through which changes in environmental conditions affecting the growth of microorganism are sensed, transmitted and converted into mechanisms controlling the production of ...

Secondary Metabolites of Basidiomycetes

2009
Basidiomycetes, a major class of higher fungi adapted to many different climates, habitats, and substrates, have developed a rich and very diverse secondary metabolism. Its products differ in biogenetic origin and structure remarkably from the metabolites of ascomycetes or other prolific producers of secondary metabolites like actinomycetes or ...

Detection of Novel Secondary Metabolites

Critical Reviews in Biotechnology, 1991
The study of antibiotics and other fermentation products has shown that a seemingly unlimited number of compounds with diverse structures are produced by microorganisms. The continued high rate of discovery of new chemical entities, in the light of the abundance of microbial products already described, is due to creative screening procedures that ...

Secondary Metabolites of Ferns

2018
This chapter presents new chemical data on the structure, characteristics, content, and probable biological functions of the secondary metabolites of ferns. The number of isolated new phenolics and terpenoids is high, but the occurrence of alkaloids is very limited; some qualitative data are uncertain.

Cyanobacterial Secondary Metabolites

1996
Blue-green algae (cyanobacteria) are among the most primitive of organisms, having an evolutionary history spanning some four billion years. These procaryotic, photosynthetic microorganisms, which have the morphology and physiology of both bacteria and plants, are ubiquitous and adaptive to a wide variety of environments, including hot springs and ...

Secondary metabolite production

1992
In the past it was frequently assumed that plant cells, mass produced in vitro, could serve as sources of valuable metabolites. It was envisaged that by strictly controlled manipulation of the physical environment and of the nutrient medium, cells in vitro could be induced to produce the desired products in large quantities.

Quantification of Secondary Metabolites

2015
Plants are a rich source of secondary metabolites that have medicinal and aromatic properties. Secondary metabolites such as alkaloids, iridoids and phenolics generally produced by plants for their defence mechanisms have been implicated in the therapeutic properties of most medicinal plants.
