This domain is the catalytic domain of dinoflagellate luciferase . Luciferase is involved in catalysing the light emitting reaction in bioluminescence. The structure of this domain has been solved [1]. The core part of the domain is a 10 stranded beta barrel that is structurally similar to lipocalins and FABP [1].	Domain

This domain is found associated with the the catalytic domain of dinoflagellate luciferase . Luciferase is involved in catalysing the light emitting reaction in bioluminescence. The structure of this domain has been solved [1]. This domain has a three helix bundle structure that holds four important histidines that are thought to play a role in the pH regulation of the enzyme.	Domain
