(Phys.org) -- The crystal structure of a protein in a bacterium being studied for its renewable energy potential suggests that the protein's biological function may be unique to a process leading to hydrogen gas production, according to researchers from Pacific Northwest National Laboratory and Brookhaven National Laboratory. They determined the structure for a protein that falls into a family of proteins with a "Domain of Unknown Function," annotated DUF269, from Cyanothece 51142, a photosynthetic bacterium with a completely different lifestyle in the day and the night.
