Abstract
The present invention provides industrially useful luciferase. Mutant luciferase of the invention is produced by culturing a microorganism belonging to the genus Escherichia which harbors a recombinant DNA containing the mutant luciferase gene of a firefly. Mutant luciferase can produce red, orange or green color of light which can not be produced by wild type luciferase. Mutant luciferase can be used to measure ATP accurately in a colored solution such as red (e.g., blood), orange, or green in which wild-type luciferase has not provided reliable results.
