GTPases have long been considered key examples of undruggable proteins. While this has been overcome for K-Ras using #CovalentInhibitors, for many other family member #DrugDevelopment has not been shown.

Congratulations to Johannes Morstein on winning one of the @GDCh_BioChem Young Scientist Awards for his work addressing this challenge by identifying druggable, allosteric pockets in several GTPases.

Can the functions of #metalloenzymes be further improved using non-canonical amino acids?

In her talk at #Biochemistry2026, Alexandra Deliz Liang talked about the usage of genetic code expansion in order to improve the activity of metalloenzymes using e.g. hydrophobic tuning.
