Crystal Structure of BAP (IMAGE) DOE/Argonne National Laboratory Caption An Argonne/University of Tennessee research team reconstructed the crystal structure of BAP, a protein involved in the process by which marine archaea release carbon, to determine how it functioned, as well as its larger role in carbon cycling in marine sediments. Research was performed at the Advanced Photon Source and the Advanced Protein Characterization Facility.
