Water and sunlight the formula for sustainable fuel

s to store iron, but the team removed the iron and replaced it with the abundant metal, manganese, to closely resemble the water splitting site in photosynthesis.

The protein also binds a haem group, which the researchers replaced with a light-sensitive pigment, Zinc Chlorin.

When they shone light onto the modified ferritin, there was a clear indication of charge transfer just like in natural photosynthesis.

The possibilities inspired visionary researcher Associate Professor Warwick Hillier, who led the research group until his death from brain cancer, earlier this year.

"Associate Professor Hillier imagined modifying E. coli so that it expresses the gene to create ready-made artificial photosynthetic proteins. It would be a self-replicating system all you need to do is shine light on it," Dr Hingorani said.
