Engineering Microbes for Plant Polyketide Biosynthesis
Polyketides are an important group of secondary metabolites, many of which have important industrial applications in the food and pharmaceutical industries. Polyketides are synthesized from one of three classes of enzymes differentiated by their biochemical features and product structure: type I, type II or type III polyketide synthases (PKSs). Plant type III PKS enzymes, which will be the main...
متن کاملMetabolic engineering for plant natural product biosynthesis in microbes.
Plant natural products (NPs) not only serve many functions in an organism's survivability but also demonstrate important pharmacological activities. Isolation of NPs from native sources is frequently limited by low abundance and environmental, seasonal, and regional variation while total chemical synthesis of what are often complex structures is typically commercially infeasible. Reconstruction...
متن کاملMechanistic Aspects of Biosynthesis of Nanoparticles by Several Microbes
While a large number of microbial species are capable of producing metal NPs, mechanism of nanoparticle biosynthesis is very important. The metabolic complexity of viable microorganisms complicates the analysis and identification of active species in the nucleation and growth of metal NPs. Strategies such as enzymatic oxidation or reduction, sorption on the cell wall and, in some cases, subsequ...
متن کاملDesigner biomass for next-generation biorefineries: leveraging recent insights into xylan structure and biosynthesis
Xylans are the most abundant noncellulosic polysaccharides in lignified secondary cell walls of woody dicots and in both primary and secondary cell walls of grasses. These polysaccharides, which comprise 20-35% of terrestrial biomass, present major challenges for the efficient microbial bioconversion of lignocellulosic feedstocks to fuels and other value-added products. Xylans play a significan...
متن کاملLice, Humans, and Microbes
Lice are small, wingless, minor ectoparasites of mammals and birds. More than 540 blood-sucking lice (Phthiraptera: Anoplura) have been described with each host having its own type of louse, suggesting the cospeciation of the lice species with their host. Among these, two lice species from two different genera infest humans: Pediculus humanus and Phthirus pubis (pubic “crab” l...
