Characterization of Triterpene Saponin Glycyrrhizin Transport by Glycyrrhiza glabra

open access: yesPlants, 2022
Glycyrrhizin (GL), a triterpene compound produced by Glycyrrhiza species, is a crucial pharmacologically active component of crude drugs. In contrast to the biosynthesis of GL in plants, little is known about GL transport and accumulation in plants.

Interference between ER stress-related bZIP-type and jasmonate-inducible bHLH-type transcription factors in the regulation of triterpene saponin biosynthesis in Medicago truncatula

open access: yesFrontiers in Plant Science, 2022
Triterpene saponins (TS) are a structurally diverse group of metabolites that are widely distributed in plants. They primarily serve as defense compounds and their production is often triggered by biotic stresses through signaling cascades that are ...

Identification of early quassinoid biosynthesis in the invasive tree of heaven (Ailanthus altissima) confirms evolutionary origin from protolimonoids

open access: yesFrontiers in Plant Science, 2022
The tree of heaven, Ailanthus altissima (MILL.) SWINGLE, is a globally invasive plant known to secrete allelopathic metabolites called quassinoids. Quassinoids are highly modified triterpenoids.

Identification and characterization of an acyl-CoA:triterpene acyltransferase activity in rabbit and human tissues.

open access: yesJournal of Lipid Research, 1991
Rabbit and human tissues contain substantial amounts of an unusual lipid, a fatty acid ester of a pentacyclic triterpene, that is a potent in vitro inhibitor of acyl-CoA:cholesterol acyltransferase (ACAT). A possible origin of the triterpene ester is via

Role of diacylglycerol kinase in autophagy, ER biogenesis, and triterpene metabolism

open access: yesAutophagy Reports, 2022
Saccharomyces cerevisiae is widely used for producing various triterpenes by exploiting its native mevalonate/ergosterol pathway. Yeasts that accumulate phospholipids can produce more triterpenes.
