Glossary: Oplophorus luciferin = 8-benzyl-2-(4-hydroxybenzyl)-6-(4-hydroxyphenyl)imidazo[1,2-a]pyrazin-3(7H)-one

Other name(s): Oplophorus luciferase

Systematic name: Oplophorus-luciferin:oxygen 2-oxidoreductase (decarboxylating)

Comments: The luciferase from the deep sea shrimp Oplophorus gracilirostris is a complex composed of more than one protein. The enzyme's specificity is quite broad, with both coelenterazine and bisdeoxycoelenterazine being good substrates.
