(S)-malate + oxidized 2,6-dichlorophenol indophenol
the route of electrons in this assay is unclear, but it probably leads from the enzyme either directly or via quinones to 2,6-dichlorophenol indophenol. The malate-dependent 2,6-dichlorophenol indophenol reduction rate catalyzed by Helicobacter pylori membranes could be stimulated by 30 to 50% by the addition of 60 mM ubiquinone-1. This suggests that quinones play, at least in part, an intermediary role in the reduction of the dye
