Anna and Sam are X-less but they’ve done some excellent work with this project. It’s a very exciting time for enzyme designers!
New research in Science represents a notable step forward in designing enzymes from scratch. With a new approach, researchers designed an enzyme that uses a covalent intermediate to catalyze a two-step reaction, analogous to what many proteases do when breaking apart proteins.

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS, indeterminate dendritic cell histiocytosis

“Science is a human activity.” The week before chemistry laureate David Baker visited Stockholm to receive his Nobel Prize, his 101st PhD student had just graduated from his lab. For Baker, doing great science is about collaboration – he puts great effort into fostering a

While most of the work focuses on artificial systems, Adam also shows that the approach can be used to add an "off-switch" to a previously designed minibinder (Neo2) that binds to the IL-2 receptor. Adams design binds the receptor tightly, but can be removed by adding competitor

Adam combined computational protein design with some smart concepts to generate a system in which the competition occurs via a conformational change.

While active (toehold-mediated) displacement is commonly used in DNA nanotech, competition in protein-protein interactions requires the original partner to dissociate before the competitor can bind, which is slow and can be limiting if spontaneous dissociation would be harmful.

I'm thrilled to share @adam_broerman's preprint @UWproteindesign about facilitated dissociation in designed proteins. In his designs, a competitor can actively displace a tightly bound partner, speeding up dissociation by several orders of magnitude. https://t.co/7dI9FvHnIS

Protein design has focused primarily on the design of ground states, ensuring they are sufficiently low energy to be highly populated[1][1]. Designing the kinetics and dynamics of a system requires,...

Finally, out in @ScienceMagazine today, our work on de novo protein design. Together with @HattoriLab , @sokrypton & @hendrik_dietz we showed how we can drastically improve AF2 based hallucination, surpassing, or reaching SOTA diffusion models https://t.co/VSbKR3JQLS
