The measurement of respiratory chain enzyme activities is an integral part of basic research as well as for specialized examinations in clinical biochemistry. Most of the enzymes use ubiquinone as one of their substrates. For current in vitro measurements, several hydrophilic analogues of native ubiquinone are used depending on the enzyme and the workplace. We tested five readily available commercial analogues and we showed that Coenzyme Q2 is the most suitable for the measurement of all tested enzyme activities. Use of a single substrate in all laboratories for several respiratory chain enzymes will improve our ability to compare data, in addition to simplifying the stock of chemicals required for this type of research.
Résumé
La mesure des activités des enzymes de la chaîne respiratoire fait partie intégrante de la recherche fondamentale ainsi que des examens spécialisés en biochimie clinique. La plupart des enzymes utilisent l’ubiquinone comme l’un de leurs substrats. Pour les mesures in vitro actuelles, plusieurs analogues hydrophiles de l’ubiquinone native sont utilisés en fonction de l’enzyme et du lieu de travail. Nous avons testé cinq analogues commerciaux facilement disponibles et avons montré que la coenzyme Q2 était la mieux adaptée à la mesure de toutes les activités enzymatiques testées. L’utilisation d’un seul substrat dans tous les laboratoires pour plusieurs enzymes de la chaîne respiratoire améliorera notre capacité à comparer les données, tout en simplifiant le stock de produits chimiques nécessaires à ce type de recherche.
