Leaflet-specific phospholipid imaging using genetically encoded proximity sensors - Nature Chemical Biology An approach combining bioorthogonal chemistry with genetically encoded fluorogen-activating proteins enables subcellular imaging of phospholipids and glycans, as well as the visualization of lipid tra...

Very excited to share new work out today in @natchembio.nature.com on a new approach - FACES - for selectively imaging of phospholipids and other biomolecules at spatial resolutions down to individual membrane leaflets (1/n) www.nature.com/articles/s41...

Glycopolymers stabilize protein folding and protein-protein interactions via enthalpic interactions Macromolecular crowding is ubiquitous to physiological environments, perturbing the thermodynamics and kinetics of proteins via excluded volume and nonspecific chemical interactions. While crowding ha...

Thrilled to share this manuscript from my lab where we looked at how glycopolymers that compose the glycocalyx influence protein folding and protein-protein interactions via macromolecular crowding.

TLDR: The Glycocalyx stabilizes protein folding and PPIs

Targeted Protein Acetylation Through Chemically Induced Proximity ConspectusProtein acetylation is a pervasive and reversible post-translational modification (PTM) that impacts various protein features including stability, localization, and interactions and regulate...

Happy to share our contribution to this special issue dedicated to "Proximity-Induced Chemical Biology". We provide our take on targeted protein acetylation.

Nice work Wesley and Roy!

Structural basis for the conformational protection of nitrogenase from O2 - Nature Cryo-electron microscopy of Azotobacter vinelandii FeSII–nitrogenase reveals a core complex of molybdenum–iron proteins (MoFePs), iron proteins (FePs) and FeSII, in which FeSII mediates interactions with MoFeP and FeP to position their FeS clusters in catalytically inactive but O2-protected states.

Awesome work from Sarah, @bcryo.bsky.social and friends in the Herzik Lab! It was cool to see this come together in such a short time.

I like the inclusion of a picture the actual pond in Fig. 1A of this paper! Very serene, it sets the stage well.
