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.

BREAKTHROUGH in protein structure prediction!
by Eric Martz
After decades of slow progress by many groups, in 2020, AlphaFold2 proved able to accurately predict the detailed structures of two-thirds of single protein domains from their amino acid sequences. Pictured is AlphaFold2's prediction for the ORF8 protein of SARS-CoV-2 (black), compared with a subsequently published X-ray crystallographic structure (colors). ORF8 contributes to virulence in COVID-19.

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.

The 2025 Nobel Prize in Chemistry was awarded for studies of metal-organic frameworks. Against expectations, the building blocks of metal-organic frameworks turned out to form networks with large cavities and the materials have a wide range of far-reaching practical applications.
