FruitFire: a luciferase based on a fruit fly metabolic enzyme
2023, Adams Jr., Spencer T.
Firefly luciferase is homologous to fatty acyl-CoA synthetases from insects that are not
bioluminescent. Here, we determined the crystal structure of the fruit fly fatty acyl-CoA
synthetase CG6178 to 2.5 Å. Based on this structure, we mutated a steric protrusion in
the active site to create the artificial luciferase FruitFire, which prefers the synthetic
luciferin CycLuc2 to D-luciferin by >1000-fold. FruitFire enabled in vivo bioluminescence
imaging in the brains of mice using the pro-luciferin CycLuc2-amide. The conversion of
a fruit fly enzyme into a luciferase capable of in vivo imaging underscores the potential
for bioluminescence with a range of adenylating enzymes from nonluminescent
organisms, and the possibilities for application-focused design of enzyme-substrate
pairs.
