What pLDDT means and how to read it

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

Subunit structure

Heterotetramer of a catalytic 19 kDa and a non-catalytic 35 kDa subunit
