The study titled “New Zealand glowworm bioluminescence is produced by a firefly-like luciferase but an entirely new luciferin” was a collaborative effort between Otago’s Chemistry and Biochemistry departments.

Lead authors Doctors Oliver Watkins and Miriam Sharpe, working with Professors Nigel Perry (Chemistry) and Kurt Krause (Biochemistry), have discovered that the New Zealand glowworms produce their light using a chemical reaction that is different to all other glowing creatures like fireflies. All light made by living creatures comes from chemical reactions that take place in enzymes called luciferases.

“What we have discovered is that the chemical, called a luciferin, which makes light in New Zealand glowworms, is unique, not used by any other glowing organism. However, the glow-worm luciferase enzyme is related to enzymes already found in other bioluminescent organisms like fireflies,” says Dr Sharpe.

“No-one expected that this type of luciferase could make light with more than one kind of luciferin chemical.”

Professor Krause says these findings are an important addition to our knowledge of glow-worms and notes that, the chemical that creates their glow could have important uses in the medical biotechnology sector.

“For instance, the light-generation taking place in the glowworm’s ‘taillight’ could potentially be used in
