Abstract

Flying Colours Fireflies communicate using coloured light that is emitted when an electronically excited oxyluciferin species — made by the enzyme luciferase — relaxes to its groundstate. Point mutants of the enzyme can dramatically alter the colour of this ‘bioluminescence’, and though the luciferase X-ray crystal structure has been solved previously, the exact nature of this colour change had eluded biologists. Nakatsu et al. have now solved the X-ray structures of luciferase in several different states, and identify a specific conformational change in an isoleucine residue as the trigger for changes in bioluminescence colour.
