Conformational free energy landscape of sorting signal peptides in complex with bacterial sortases
Sortase enzymes are cysteine transpeptidases that anchor surface proteins to the cell wall of Gram-positive bacteria. These enzymes are widely used in protein engineering applications because they…

Sortase A-Mediated Farnesylation of Cdc42 In Vitro

May 21, 2026 at 7:32 AM
Paper out in collaboration with the Liedewij Laan group
Starting from an interest in PTMs and protein modification, we developed a sortase substrate for farnesyl incorporation. And learned, the hard way, how difficult these compounds are to work with, despite their simple structure 😳
May 19, 2026 at 7:43 AM
Our paper is out in ACS Synthetic Biology!!

A major bottleneck in reconstituting cell polarity is obtaining functional prenylated Cdc42. Here, we developed a Sortase-based strategy to farnesylate Cdc42, which retains membrane binding and regulatory GTPase activity.
