Abstract:ObjectivesFirefly luciferase, one of the most extensively studied enzymes, has numerous applications. However, luciferase activity is inhibited by sodium chloride. This study aims to expand the applications of firefly luciferase in the presence of sodium chloride.ResultsWe first obtained two mutant luciferase enzymes whose inhibition were alleviated and identified these mutations as Val288Ile and Glu488Val. Under dialysis condition (140 mM sodium chloride), the wild type was inhibited to 44% of its original ac… Show more
