Diphosphomevalonate decarboxylase , most commonly referred to in scientific literature as mevalonate diphosphate decarboxylase.This enzyme converts mevalonate 5-diphosphate (MVAPP) to isopentenyl diphosphate (IPP) through ATP dependent decarboxylation.[1] The two substrates of this enzyme are ATP and mevalonate 5-diphosphate, whereas its 4 products are ADP, phosphate, isopentenyl diphosphate, and CO2.Mevalonate diphosphate decarboxylase catalyzes the final step in the mevalonate pathway. The mevalonate pathway is responsible for the biosynthesis of isoprenoids from acetate.[2] This pathway plays a key role in multiple cellular processes by synthesizing sterol isoprenoids, such as cholesterol, and non-sterol isoprenoids, such as dolichol, heme A, tRNA isopentenyltransferase, and ubiquinone.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA500275) at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
