Le coenzyme Q est une molécule lipophile rédox rencontrée chez les eucaryotes et chez la plupart des procaryotes. La structure de Q correspond à une benzoquinone substituée par une chaîne polyisoprényle dont la longueur varie selon les organismes. Q joue le rôle de transporteur d'électrons dans les chaînes respiratoires d'où provient la plupart de l'énergie de la cellule. La biosynthèse de Q chez la bactérie Escherichia coli comporte huit étapes et implique au moins neuf protéines (UbiA-UbiH et UbiX). Trois réactions d'hydroxylation sont nécessaires pour la biosynthèse de Q8 en conditions aérobies. Alors que les protéines UbiH et UbiF présentent des homologies de séquence avec des monooxygénases à flavine connues pour catalyser des réaction...
