Metabolic regulation and engineering of artemisinin biosynthesis in A. annua

Medicinal Plant Biology, 2023
Artemisinin is a potent anti-malarial sesquiterpene lactone that is naturally biosynthesized in glandular trichomes of a Chinese herbal plant, Artemisia annua. Although semi-synthesis of artemisinin in yeast has been feasible, at present the A.

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

The multifunctional autophagy pathway in the human malaria parasite, Plasmodium falciparum. [PDF]

, 2013
Autophagy is a catabolic pathway typically induced by nutrient starvation to recycle amino acids, but can also function in removing damaged organelles. In addition, this pathway plays a key role in eukaryotic development. To date, not much is known about

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
