COQ3 (Dihydroxyhexaprenylbenzoate Methyltransferase, 3,4-dihydroxy-5-hexaprenylbenzoate Methyltransferase, Hexaprenyldihydroxybenzoate Methyltransferase, Mitochondrial, DHHB Methyltransferasem, DHHB-MTase, DHHB-MT, COQ3, UG0215E05) (HRP)

Ubiquinone, also known as coenzyme Q, or Q, is a critical component of the electron transport pathways of both eukaryotes and prokaryotes (Jonassen and Clarke, 2000 [PubMed 10777520]). This lipid consists of a hydrophobic isoprenoid tail and a quinone head group. The tail varies in length depending on the organism, but its purpose is to anchor coenzyme Q to the membrane. The quinone head group is responsible for the activity of coenzyme Q in the respiratory chain. COQ3 is an O-methyltransferase required for 2 steps in the biosynthetic pathway of coenzyme Q. This enzyme methylates an early coenzyme...
