Research Abstract |
We measure the bioluminescent activities and determine the crystal structures of G326S and Y257A firefly luciferase mutants which emit red light. In the result, it is supposed that the emission color change from yellow-green to red and the decrease of the emission are caused by the energy loss of the excited oxyluciferin. In addition we determine the crystal structure of luciferin regenerating enzyme, which controls the emission reaction in firefly.
