additional information | construction of a chimeric enzyme luc2 that contains the N-domain of Photinus pyralis luciferase joined to the C-domain of Luciola italica luciferase, the recombinant chimeric enzyme shows 2fold enhanced activity and 1.4fold greater bioluminescence quantum yield compared to the wild-type Photinus pyralis luciferase. Further engineering to enhance thermal and pH stability produces a different luciferase called PLG2, that shows 4.4fold enhanced activity and 2.2fold greater bioluminescence quantum yield compared to the wild-type. Five amino acid changes based on Luciola italica are the main determinants of the improved bioluminescence properties | Luciola italica |
