A research group comprising Brazilian and Japanese scientists has discovered how luciferase produced by the railroad worm Phrixothrix hirtus emits red light. Luciferase is an enzyme that catalyzes the oxidation of luciferin in fireflies, producing oxyluciferin and enabling fireflies to emit light. Differences in the molecular structures explain the different colors of this bioluminescence in different species.
