Mevalonate kinase (MVK) is an enzyme involved in biosynthesis isoprenoids and is necessary for the conversion of mevalonate to mevalonate-5-phosphate in the presence of Mg 2+. Downstream of this enzyme, mevalonate-5-phosphate is converted into non-sterol (geranylgeranyl, farnesyl) or sterol isoprenoids (cholesterol). MKD is due to a pathogenic ...
Mevalonate is a key intermediate, and mevalonate kinase a key early enzyme, in isoprenoid and sterol synthesis. [6] As the second enzyme in the Mevalonate pathway, it catalyzes the phosphorylation of Mevalonic acid to produce Mevalonate-5-phosphate. [ 8 ]
mevalonate-3-phosphate-5-kinase: Mevalonate-3-phosphate is phosphorylated at the 5-OH position to yield mevalonate-5-phosphate (also called phosphomevalonic acid). 1 ATP is consumed. phosphomevalonate kinase: mevalonate-5-phosphate is phosphorylated to yield mevalonate-5-pyrophosphate. 1 ATP is consumed. mevalonate-5-pyrophosphate decarboxylase
More than 38 million Americans have diabetes, and between 90% and 95% of them have type 2 diabetes. While most are adults over the age of 45, an increasing number of children and teens are also ...
Some federal health websites and reports have reappeared after the Trump administration ordered a pause on public communications from agencies like the CDC, FDA, and NIH in January.
For people with healthy cholesterol levels, eating a moderate amount of dairy products (up to 200 grams per day), whether low or full-fat, may not negatively affect their heart disease risk.
An excellent review on regulation of the mevalonate pathway by Nobel Laureates Joseph Goldstein and Michael Brown adds specifics: HMG-CoA reductase is phosphorylated and inactivated by an AMP-activated protein kinase, which also phosphorylates and inactivates acetyl-CoA carboxylase, the rate-limiting enzyme of fatty acid biosynthesis.
