En enzyme system has been found in peas which converts mevalonic acid to isoprenoid compounds. Among the intermediates in such conversion are mevalonic acid-5-phosphate and pyrophosphate, isopentenyl pyrophosphate and dimethylallylpyrophosphate. Among the products formed by the system are the pyrophosphates of geraniol, farnesol, nerolidol and higher isoprenoid alcohols.

The sesquiterpene (+)-valencene, with its flavor and diverse biological functions, holds promise for applications in the food, fragrance, and pharmaceutical industries. However, the low concentration in nature and high cost of extraction limit its application. This study aimed to construct a microbial cell factory to efficiently produce (+)-valencene.

(-)-α-Bisabolol exhibits analgesic, anti-inflammatory, and skin-soothing properties and is widely applied in the cosmetic and pharmaceutical industries. The use of plant essential oil distillation or chemical synthesis to produce (-)-α-bisabolol is both inefficient and unsustainable. Currently, the microbial production of (-)-α-bisabolol mainly relies on and as chassis strains; however, high concentrations of (-)-α-bisabolol have certain toxicity to the strain.

Utilization of microbial hosts to produce natural plant products is regarded as a promising and sustainable approach. However, achieving highly efficient production of terpenoids using microorganisms remains a significant challenge. Here, mevalonate, a building block of terpenoids, was used as a demo product to explore the potential metabolic constraints for terpenoid biosynthesis in .

The synthesis of photocaged substrates of the biologically important enzyme HMG-CoA reductase is reported. HMG-CoA bearing a -hydroxyphenacyl (pHP) photocage moiety was synthesized in an overall yield of 14% over seven steps in addition to caged forms of mevalonate and mevaldehyde. The absorption maximum and quantum yield for the decaging of the photocaged compounds are dependent on pH with a λ of 330 nm and a ϕ of 5%, respectively, at pH 9.

Liver fibrosis is a well-established risk factor for liver cancer development. Despite extensive mechanistic studies on liver fibrosis, the role of the immune cell network in fibrotic disease remains poorly understood. In this study, we demonstrate that regulatory T cells (Tregs) are involved in preventing liver fibrosis by regulating the mevalonate pathway.
