As life is more than 2D, Proteopedia helps to bridge the gap between 3D structure & function of biomacromolecules

Often it is difficult to utilize the wealth of information found in 3D biomacromolecular structures. Proteopedia's goal is to present structure/function information on these molecules in a user-friendly manner to a broad scientific audience.

Coronavirus Spike Protein Membrane Fusion

by Eric Martz
SARS-CoV-2 spike protein "spears" the host membrane with a fusion peptide and drags the virus envelope membrane transmembrane domain close to the host membrane, initiating fusion. This moves the virus RNA genome into the host cell, initiating infection.

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.
