The structural origin and biological function of pH-sensitivity in firefly luciferases.
TLDR
Experimental evidence suggest that the residual red light emission in pH-sensitive luciferases could be a vestige that may have biological importance in some firefly species, and the potential utility of pH-sensitivity for intracellular biosensing applications is considered.

Cloning, sequence analysis, and expression of active Phrixothrix railroad-worms luciferases: relationship between bioluminescence spectra and primary structures.
TLDR
PhrixothrixLuciferases do not undergo the typical red shift suffered by firefly luciferases upon decreasing pH, a property which might be related to the many amino acid residues shared in common between railroad-worm and click-beetle luciferase.

Cloning and Molecular Characterization of the cDNA for the Brazilian Larval Click‐beetle Pyrearinus termitilluminans Luciferase
TLDR
The region between residues 223 and 247 that contains the putative active site for BL color determination showed a higher degree of homology among click‐beetle luciferases that elicit closer BL colors.

Larval Tenebrio molitor (Coleoptera: Tenebrionidae) Fat Body Extracts Catalyze Firefly D‐Luciferin‐ and ATP‐Dependent Chemiluminescence: A Luciferase‐like Enzyme *
TLDR
The data suggest that this chemiluminescence results from a ligase with luciferase activity, which is strongly inhibited by AMP, luciferin 6′‐ethyl ether and sodium pyrophosphate, well‐known firefly lucifer‐ase inhibitors.
