Biosynthesis of cholesterol from mevalonate
WebMevalonate Fermentation. Mevalonate, a ubiquitous biosynthetic intermediate of isoprenoids, is utilized as a moisturizer in cosmetics and a chemical in biochemical research. The current supply of optically active mevalonate relies on fermentation production by the yeast, Saccharomycopsis fibuligera ADK 8107, whose mevalonate productivity is 19 ... WebJan 24, 2024 · There are still gaps in our understanding of the complex processes by which p53 suppresses tumorigenesis. Here we describe a novel role for p53 in suppressing the mevalonate pathway, which is responsible for biosynthesis of cholesterol and nonsterol isoprenoids. p53 blocks activation of SREBP-2, the master transcriptional regulator of …
