Lifecycle of SARS-CoV-2

What happens if a SARS-CoV-2 coronavirus enters your lung? This molecular animation visualises how the virus particle can take over the host cell and turns it into a virus factory. Eventually, the host cell produces so many viral particles that it dies and releases numerous new virus particles. >>> Visit this page >>>

Opening a Gate to Human Health

by Alice Clark (PDBe)
In the 1970s, an exciting discovery of a family of medicines was made by the Japanese scientist Satoshi Ōmura. One of these molecules, ivermectin, is shown in this artwork bound in the ligand binding pocket of the Farnesoid X receptor, a protein which helps regulate cholesterol in humans. This structure showed that ivermectin induced transcriptional activity of FXR and could be used to regulate metabolism.

Structure of Anticancer Ruthenium Half-Sandwich Complex Bound to Glycogen Synthase Kinase 3ß

G Atilla-Gocumen, L Di Costanzo, E Meggers. J Biol Inorg Chem. 2010 doi: 10.1007/s00775-010-0699-x
A crystal structure of an organometallic half-sandwich ruthenium complex bound to glycogen synthase kinase 3ß (GSK-3ß) reveals that the inhibitor binds to the ATP binding site via an induced fit mechanism utilizing several hydrogen bonds and hydrophobic interactions. Importantly, the metal is not involved in any direct interaction with the protein kinase but fulfills a purely structural role.
