1.13.12.8	Watasenia luciferin + O2	-	
1.13.12.8	Watasenia luciferin + O2	coelenterazine disulfate is the Watasenia scintillans luciferin substrate, and the reaction requires ATP, Mg2+ and molecular oxygen. Protein microcrystals in the arm photophores catalyse the bioluminescent reaction using ATP and the substrate coelenterazine disulfate
