摘要：

Various long-chain choline derivatives, differing in the length of the hydrocarbon backbone, have been synthesized. The influence of these compounds on the activity of firefly luciferase has been studied. Whereas C-4-C-10 derivatives do not influence enzyme activity, C-12-C-18 derivatives inactivate luciferase rapidly and irreversibly. It is suggested that interaction between the enzyme and these compounds has a hydrophobic nature. Phospholipids stabilize luciferase against the inactivation by these derivatives. It was shown that long-chain choline derivatives with a backbone of 10 carbon atoms and more can be used for ATP extraction and further bioluminescent microassay in the presence of phospholipid additives as the agents which stabilize luciferase.
