We engineered bacteriorhodopsin to be soluble. It binds retinal and can photocycle! X-ray structure reveals conserved binding pocket with 0.8 ร all atom RMSD to WT BR. All this became possible due to hard work by Andrey Nikolaev and the team ๐

I am happy to share a review I recently wrote on the design of peptide binders. It gives an overview of experimentally validated tools and discusses the challenges of why peptide design is more difficult than the design of classical protein binders.

65 years after Peter Mitchellโs chemiosmotic theory, we report an association between ATP synthase and the electron transport chain. In the preprint led by
@longzhou88.bsky.social
, we describe a large supercomplex and show how the supramolecular organization contribute to oxidative phosphorylation ๐งต

New preprint: We checked whether AlphaFold and its great freely available analogs (including the recent Protenix) can predict the effects of ligand charge. Surprisingly, the predictions sometimes depended on the input format stronger than on the charge! (1/6)

A ligand-binding sensor domain got a tiny insertion from cytochrome c, which contained a heme-binding motif, and now it is a nitric oxide sensor. As simple as that:

The bureaucracy of science has grown so much, the system is collapsing upon itself: Scientists have become administrators of grants rather than spending time on science. Paid administrators are demanding even more administrative work from scientists. Administrators are eating the science budget.

For high-resolution studies of intracellular crystals, in-house electron diffraction methods are shown to be orders of magnitude more efficient than serial X-ray crystallography regarding the total crystal material required and the radiation dose deposited.
