Generally, firefly luciferases have some similarities with Acyl-CoA ligases and some peptide synthetases despite having different cellular effects. In fixing the structure of L. cruciata luciferase, the analog of a potent aminoacyl-tRNA synthetases (DLSA) was successfuly utilized to represent a stable oxyluciferin intermediate.<ref name="structure">PMID:16541080 </ref>.{{STRUCTURE_2d1s| PDB=2d1s ||SIZE=400| SCENE=Luciferase/2d1s/2 |CAPTION= 2d1s, resolution 1.30Å (<scene name='Luciferase/2d1s/2'>default scene</scene>). }} | |||

The DLSA occupied the active site of the luciferase, which is composed of an α-helix (residues 248-260) and four short β-sheets (residues 286-289, 313-316, 339-342 and 351-353. Ile288 has been implicated as an important residue in determining the hydrophobicity of the active site environment, and through orientation of the product oxyluciferin, the bioluminescent colour. <ref name="structure" />. | The DLSA occupied the active site of the luciferase, which is composed of an α-helix (residues 248-260) and four short β-sheets (residues 286-289, 313-316, 339-342 and 351-353.
