VARIANT LUCIFERASE, VARIANT LUCIFERASE GENE, NOVEL RECOMBINANT DNA AND PROCESS FOR PRODUCING VARIANT LUCIFERASE

摘要

The present invention relates to a variant luciferase having improved luminescence sustention when compared with a wild type luciferase; a variant luciferase gene encoding the amino acid sequence of this luciferase; a recombinant DNA characterized in that it is constructed by insertion of this variant luciferase gene into a vector DNA; a transformant or a transductant comprising this recombinant DNA; and a method for producing a variant luciferase, which comprises culturing the above transformant or transductant in a medium and collecting the variant luciferase from the culture product.
