Decaprenylphospho-beta-D-ribofuranose 2-oxidase (EC 1.1.98.3, decaprenylphosphoryl-beta-D-ribofuranose 2'-epimerase, Rv3790, DprE1) is an enzyme with systematic name trans,octacis-decaprenylphospho-beta-D-ribofuranose:FAD 2-oxidoreductase. [1] [2] This enzyme catalyses the following chemical reaction

trans,octacis-decaprenylphospho-beta-D-ribofuranose + FAD trans,octacis-decaprenylphospho-beta-D-erythro-pentofuranosid-2-ulose + FADH2

This enzyme from the bacterium Mycobacterium smegmatis participates in epimerization of trans,octacis-decaprenylphospho-beta-D-ribofuranose to trans,octacis-decaprenylphospho-beta-D-arabinoofuranose.

<span class="mw-page-title-main">Pyruvate dehydrogenase complex</span> Three-enzyme complex responsible for pyruvate decarboxylation

Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes that converts pyruvate into acetyl-CoA by a process called pyruvate decarboxylation. Acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration, and this complex links the glycolysis metabolic pathway to the citric acid cycle. Pyruvate decarboxylation is also known as the "pyruvate dehydrogenase reaction" because it also involves the oxidation of pyruvate.

In biochemistry, flavin adenine dinucleotide (FAD) is a redox-active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group, which may be in the form of FAD or flavin mononucleotide (FMN). Many flavoproteins are known: components of the succinate dehydrogenase complex, α-ketoglutarate dehydrogenase, and a component of the pyruvate dehydrogenase complex.

<span class="mw-page-title-main">Tetrahydrocannabinolic acid synthase</span> Enzyme

Tetrahydrocannabinolic acid (THCA) synthase is an enzyme responsible for catalyzing the formation of THCA from cannabigerolic acid (CBGA). THCA is the direct precursor of tetrahydrocannabinol (THC), the principal psychoactive component of cannabis, which is produced from various strains of Cannabis sativa. Therefore, THCA synthase is considered to be a key enzyme controlling cannabis psychoactivity. Polymorphisms of THCA synthase result in varying levels of THC in Cannabis plants, resulting in "drug-type" and "fiber-type" C. sativa varieties.
