Short name: Luciferase_hlx-bundle_domain

Overlapping homologous superfamilies

Domain relationships



This domain is found associated with the the catalytic domain of dinoflagellate luciferase. Luciferase is involved in catalysing the light emitting reaction in bioluminescence. 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 [PMID: 15665092].
