Function

function

Catalytic subunit of oplophorus-luciferin 2-monooxygenase. Oxidoreductase that converts coelenterazine (the oplophorus luciferin) to coelenteramide under emission of blue light with a maximum at 454 nm. Is also active with bisdeoxycoelenterazine.

Miscellaneous

The shrimp has luminous glands at the base of its antennae and legs, and ejects a cloud of brightly luminescent secretion from the base of its antennae upon stimulation.
