New research led by UC San Diego’s Scripps Institution of Oceanography highlights the critical role of mangroves in protecting coastal communities from the devastating effects of climate change—particularly hurricanes.
Diversity-generating retroelements are found in the genomes of microorganisms across the globe — from the arctic permafrost to Yellowstone’s hot springs and the human gut. DGRs are able to accelerate the evolution of proteins to help microorganisms adapt to changing environments. Using cryogenic electron microscopy, Partho Ghosh’s lab at UC San Diego has figured out the first steps of this accelerated evolution by visualizing the relevant proteins and RNA.
There are only two ways of fixing nitrogen, one industrial and one biological. To better understand a key component of the biological process, University of California San Diego Professor of Chemistry and Biochemistry Akif Tezcan and Assistant Professor of Chemistry and Biochemistry Mark Herzik took a multi-pronged approach. Their work appears in Nature.
Ramesh Rao, director of the UC San Diego Qualcomm Institute, sits down with Shane Cybart, director of CalIT2 Riverside, for a wide-ranging discussion on quantum and other advanced computing methods.
Nonribosomal peptide synthetase (NRPS) enzymes are essential in creating important medications, such as penicillin and cyclosporine. Because of their large size, complex design and changing shapes, NRPS enzymes are difficult to study. In recent years, the lab of UC San Diego Professor of Chemistry and Biochemistry Michael Burkart has developed crosslinking tools to trap the enzyme at specific steps, freezing them in place, making them easier to visualize.
Much of our knowledge of the protein PD-1, a leading cancer treatment target, comes from studies in mice. In a comprehensive assessment of PD-1, researchers have found that PD-1 in mice is significantly weaker than the human version, providing new information on how cancer treatments are developed.
