Atomic-Level Snapshot Catches Protein Motor in Action

The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) using a state-of-the-art protein crystallography beamline at the Advanced Light Source (ALS). These protein motors play pivotal roles in gene expression and replication, and are vital to the survival of all biological cells, as well as infectious agents, such as the human papillomavirus, which has been linked to cervical cancer.
