We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Coronavirus COVID-19

A novel coronavirus was found to be the cause of a respiratory illness first detected in Wuhan, China in 2019. 3D structural studies are aiding scientists to understand how the coronavirus infects humans and helping to find new ways to treat the viral spread (video by Fusion Animation).

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.

Touch-Sensitive Channel

Touching stretches cell membranes, opening mechanosensitive ion channels, leading to sensation by the nervous system. Pictured is the transmembrane region of a similar channel in bacteria. When closed, the narrow opening is lined by hydrophobic amino acid sidechains, making it non-conductive to ions.
