Due to the strict enantioselectivity of firefly luciferase, only d-luciferin can be used as a substrate for bioluminescence reactions. Unfortunately, luciferin racemizes easily and accumulation of nonluminous l-luciferin has negative influences on the light emitting reaction. Thus, maintaining the enantiopurity
