1.1.5.4	2-methyl-1,4-naphthoquinone	reduction of 2,6-dichlorophenol indophenol by solubilized enzyme is activated significantly by addition of the quinones decylubiquinone, duroquinone, 2-methyl-1,4-naphthoquinone (vitamin K3), ubiquinone-0 and ubiquinone-1. Optimal activation is observed with ubiquinone-1	287733	
1.1.5.4	decylubiquinone	reduction of 2,6-dichlorophenol indophenol by solubilized enzyme is activated significantly by addition of the quinones decylubiquinone, duroquinone, 2-methyl-1,4-naphthoquinone (vitamin K3), ubiquinone-0 and ubiquinone-1. Optimal activation is observed with ubiquinone-1	287733	
1.1.5.4	duroquinone	reduction of 2,6-dichlorophenol indophenol by solubilized enzyme is activated significantly by addition of the quinones decylubiquinone, duroquinone, 2-methyl-1,4-naphthoquinone (vitamin K3), ubiquinone-0 and ubiquinone-1. Optimal activation is observed with ubiquinone-1	287733	
1.1.5.4	Lipid	activates	287733	
1.1.5.4	Phospholipid	activates	287619	
1.1.5.4	Phospholipid	activity of purified enzyme is dependent on added phospholipid	287730	
1.1.5.4	Phospholipid	in absence of either cardiolipin or vitamin K-3 the enzyme shows about 3% of maximal activity	287734	
1.1.5.4	Phospholipid	the nature of the phospholipid required to activate the enzyme depends on the nature of the quinone used in the assay system. When 2-methyl-1,4-naphthoquinone is used, a wide variety of phospholipids, including all these isolated from the organism, will activate the enzyme, but when coenzyme Q9 is used the phospholipid specificity of the enzyme is much more restricted, and the most effective activator is the unsaturated phosphatidylethanolamine isolated from the organism	696072	
1.1.5.4	ubiquinone-0	reduction of 2,6-dichlorophenol indophenol by solubilized enzyme is activated significantly by addition of the quinones decylubiquinone, duroquinone, 2-methyl-1,4-naphthoquinone (vitamin K3), ubiquinone-0 and ubiquinone-1. Optimal activation is observed with ubiquinone-1	287733	
1.1.5.4	ubiquinone-1	reduction of 2,6-dichlorophenol indophenol by solubilized enzyme is activated significantly by addition of the quinones decylubiquinone, duroquinone, 2-methyl-1,4-naphthoquinone (vitamin K3), ubiquinone-0 and ubiquinone-1. Optimal activation is observed with ubiquinone-1	287733
