Efficiently producing fatty acids and biofuels from glucose

Researchers have presented a new strategy for efficiently producing fatty acids and biofuels that can transform glucose and oleaginous microorganisms into microbial diesel fuel, with one-step direct fermentative production.

Biosynthesis of widespread pigments from bacteria revealed

Bacteria can protect themselves from the attack of free radicals using specific natural products in their membranes. The biosynthesis of one of the most common protective pigments that could also be of interest for the medical ...

What happens to magnetic nanoparticles in cells?

Although magnetic nanoparticles are being used more and more in cell imaging and tissue bioengineering, what happens to them within stem cells in the long term remained undocumented. Researchers from CNRS, the Sorbonne Université, ...

Steroid synthesis discovery could rewrite the textbooks

Steroids are essential molecules for life in all complex organisms such as animals and plants. Researchers from the VIB-UGent Center for Plant Systems Biology, the University of Technology Sydney Climate Change Cluster and ...

How protein complexes form in the cell

The formation of protein complexes is a highly organised process that does not begin with the "finished" proteins. Studies conducted by researchers at the Center for Molecular Biology of Heidelberg University (ZMBH) and the ...

Serendipitous discovery may lead to eco-friendly lubricant

Seed oil components of an ornamental flower could provide a direct pathway for designing a new class of environmentally friendly lubricants. Researchers at the School of Science at IUPUI identified the compound in the seed ...

Lipid transfer from plants to arbuscular mycorrhiza fungi

Textbooks tell us that in arbuscular mycorrhizal symbioses, the host plant supplies its fungal symbionts solely with sugars, in return for inorganic nutrients. New findings by Ludwig-Maximilians-Universitaet (LMU) researchers ...

An ancient mechanism helps a cell to resist stress

Biologists from the Lomonosov Moscow State University in collaboration with colleagues from the Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, used RNA transfection and in vitro techniques to show ...

Biosynthesis

Biosynthesis (also called biogenesis) is an enzyme-catalyzed process in cells of living organisms by which substrates are converted to more complex products. The biosynthesis process often consists of several enzymatic steps in which the product of one step is used as substrate in the following step. Examples for such multi-step biosynthetic pathways are those for the production of amino acids, fatty acids, and natural products. Biosynthesis plays a major role in all cells, and many dedicated metabolic routes combined constitute general metabolism.

The prerequisites for biosynthesis are precursor compounds, chemical energy (such as in the form ATP), and catalytic enzymes, which may require reduction equivalents (e.g., in the form of NADH, NADPH).

Commonly known complex products of biosynthesis include proteins, vitamins, and antibiotics. Most organic compounds in living organisms are built in biosynthetic pathways.
