Peter Agbo, a staff scientist in the Chemical Sciences Division, with a secondary appointment in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division, has proposed a novel method for direct ocean capture of carbon using microbes. Removing CO2 from the oceans will enable them to continue to do their job of absorbing excess CO2 from the atmosphere.
A Berkeley Lab team analyzed the genotypes and phenotypes of several Arthrobacter strains to correlate cellular functions to their location at varying depths within a single sediment core and in nearby groundwater. They found that Arthrobacter, as a genus, has remarkable flexibility in altering its suites of carbon degradation genes. This genomic variation was found to be linked to the individual strain’s environment and is the basis for Arthrobacter’s ability to break down a wide variety of complex carbon sources.
The biopolymer has far-reaching potential from medical therapeutics to replacing synthetic plastics. Armed with a deep understanding of how the enzymes makes acholetin, scientists now have a target for preventing bacterial contamination and the means to produce acholetin for a variety of purposes.
Researchers at the Scripps Institution of Oceanography in San Diego used the Berkeley Center for Structural Biology’s 8.2.2 beamline at the Advanced Light Source to identify structural details of an enzyme that produces a versatile anti-cancer molecule. By virtue of the its unique, ringed structure the molecule crosses the blood-brain barrier and could be instrumental in fighting difficult-to-access brain cancers.
Viruses have evolved a wide variety of ways to exploit parts of their host cells to avoid detection and to grow. Researchers at the Scripps Research Institute and the Berkeley Center for Structural Biology are learning more about how hepatitis C works to deceive its host cells.
