Studying the mechanical properties of viral capsids can give several insights into not only the lifecycle of the virus, but also into potential drug targets to thwart the progression of viral infection. Nanoindentation using an atomic force microscope is a useful technique for determining structural properties of small molecules and particles, and is commonly used to study viral capsids. This technique utilizes the probe of the microscope to push down on the capsid and record the forces along the indentation path. We ran this experiment in silico where we simulated the nanoindentation of Norwalk virus capsids using molecular dynamics. Running …

Phosphodiesterase 6 (PDE6) is a critical enzyme in the eyesight-signaling pathway. When activated, PDE6 hydrolyzes cGMP to GMP, which deactivates cGMP- gated ion channels, causing hyperpolarization of the cell and activating the sensory neurons responsible for vision. Within the PDE family, PDE6 is the only enzyme known to have an inhibitory subunit (PDE6-γ), which allows for the regulation of cGMP levels. When PDE6-γ is bound to PDE6, the enzyme is turned “off” and cannot catalyze cGMP. The α subunit of the G-protein transducin removes PDE6-γ and activates PDE6. PDE6 has proven problematic to isolate, making it difficult to study experimentally …
