Bacteria from cows show promising results in treating MRSA infections New research from the University of Copenhagen shows that signaling molecules from a specific Staphylococcus bacterium can treat MRSA infections as effectively as antibiotics.

Check out the write-up of our new publication in #mBio, where we profiled a large number auto-inducing peptide (AIP) signaling molecules from staphylococci.

I am extremely happy to share this new @biorxivpreprint.bsky.social, which after a long wait updates our previous preprint.
Thanks to main drivers @bgless.bsky.social and @benjaminsb.bsky.social as well as all involved colleagues and collaborators!

Peptide Backbone Cleavage and Transamidation via Thioester-to-Imide Acyl Transfer Cysteine thioesters are involved in a myriad of central biological transformations due to their unique reactivity. Despite their well-studied properties, we discovered an unexpected transamidation rea...

I'm excited to share our latest paper reporting an interesting thioester-to-imide acyl transfer reaction of S-acylcysteine.

It was great working with @sabrinaschmied.bsky.social and @christianaolsen.bsky.social

In a new preprint @chemrxiv.bsky.social, work from @bgless.bsky.social and Sabrina Schmied investigate the mechanism of a rearrangement that can lead to peptide/protein backbone cleavage.

Thanks to #LEOFondet for funding the project that led to this discovery.
