Isn't it amazing when a fresh new preprint is out on Friday? 😎🥳 Check out the fabulous work by @beatricetropea.bsky.social who gives us a clear mechanistic explanation behind the 'peculiar' structure of the LLO donor preferentially chosen by eukaryotic OST 🤓😍 doi.org/10.64898/202...
Figure 1. Structural overview of the yeast OST complex and donor-binding site. (a) 3D structure of the yeast OST complex embedded in the ER membrane (brown sticks), showing the 8 subunits as surface color coded according to the labels. The lipid-linked oligosaccharide (LLO) donor is shown in orange and the backbone of the acceptor peptide is shown with a cartoon representation in yellow. The central panel shows the 2D SNFG representation of the LLO donor, with labels specifying glycosidic linkages and the nomenclature used for the branches. Below we show the sequence of an acceptor peptide, i.e. YJR1_N99, used as substrate in all MD simulations in this work, where the target asparagine was previously characterised as efficiently glycosylated(Khaleque et al. 2025). (b) Close-up view of the donor-binding pocket from the cryo-EM structure (PDB ID: 8AGC), showing the resolved LLO donor represented in sticks (orange) and SNFG symbols and the Stt3 N539 glycan (white). (c) Close-up view of the donor-binding pocket from the 3D model used in the MD simulations with the reconstructed N-glycans. The monosaccharides resolved in the cryo-EM structure are shown in white and orange as in panel b, whereas the monosaccharides added in the reconstruction of the full LLO donor and N539 glycan are highlighted in dark orange and grey, respectively.

Un-crystallisable glyco-complexes anyone? New work led by John Klassen's lab introduces antibody masking-native mass spectrometry (AM-nMS) a spatially resolved assay that allowed us to map glycan binding sites across the SARS-CoV-2 RBD. The results match our MDs! 😜 All details glycoshape.org/blog

Carbohydrate-binding is a small profit affair, so proteins often adopt complex multidomain architectures enabling a mechanism known as 'binding cooperativity', where binding to one monomer contributes to the binding affinity of the whole systems BUT how does it actually work? 🔥 #glycotime 🧵1/4 ⬇️

Glycoheterogeneity is an aspects of glycobiology that most would class into a category between difficult and intolerable, but @benschulz.bsky.social and us love it! So we wrote a whole review in Current Opinion in Structural Biology on it 🧵1/8 ⬇️ doi.org/10.1016/j.sb...

We have some fresh and cool #glycotime 🧪 on the impact of including glycosylation explicitly in de novo binder design. Filtering the results of a recent open competition for novel binders to the Nipah Virus Glycoptrotein (NiV-G) with ReGlyco improves the pipeline efficiency significantly ⬇️
a. Structure of the Nipah Virus Glycoprotein (NiV-G) homotetramer (aa 92-602) reconstructed from cryo-EM structures (PDB 7TXZ and 7TY0) bound to broadly neutralising antibody nAH1.3 Fabs30 (not shown). Static (single) glycans 3D structures (shown with sticks in blue) were reconstructed with GlycoShape ReGlyco17, where the choice of the glycan type was guided by glycoproteomics analysis36. The visible six glycan sites on chains A, B and D are mapped onto the structure, while glycans on chain C are not labelled for clarity. b. Structure of the glycosylated NiV-G recostructured with GlycoShape ReGlyco Ensemble29 using 150 frames from the MD trajectories of each selected glycan. Rendering effect is obtained with a “long exposure” filter to reflect the glycan dynamics. Sterically constrained glycans and rigid regions of the saccharides can be identified by the darker blue colour. c. Structure of the glycosylated NiV-G as in panel b. but with each one of the 150 glycan frames shown in dark blue, to illustrate the potentially occluded volume of the NiV-G protein surface

Most biologics are glycosylated and some of them heavily. In this “fresh off the press" #glycotime preprint we look into how a filter that accounts for glycosylation explicitly in 3D can help reduce lab costs and increase the efficiency of de novo binder design pipelines. Short 🧵 ⬇️ 1/7

Silvia's simulations showed that while all epitopes expose Sia for binding, Siglec-6 recognises and binds only GM1 because of a key interaction with the membrane through W127 and K126, which orientates the V-set domain to bind the Sia through Arg122 and the terminal Gal to the C-C' loop 😎

Super interesting work from @carolynbertozzi.bskyverified.social group about the effects of glycosylation in protein structure and function at the proteome scale 🤯💥🤩 Results show that sialylation and fucosylation are crucial, which makes a lot of sense. We did some extra bits 🧐 with GlycoShape ⬇️🧵

We just did some maintenance and updates to glycoshape.org, ✅ Fancy background with floating SNFG symbols 🤩 ✅ 'Latest Updates' feed from this account on bsky 🤩 ✅ Download PDB with SASA values in Re-Glyco Ensemble 🤩 Check it out!
Front page of Glycoshape website with the new background with floating SNFG symbols representing different monosaccharides. In the website the background is animated, so check it out at https://glycoshape.orgWhen you rebuild a glycosprotein with Re-Glyco Ensemble, now you can download the multiframe PDB with SASA values in the B-values column. The structure on the left shows in blue all the accessible surface and in light blue and red inaccessible residues due to the glycan presence. The buttons below are in cyan for regular multiframe PDB download (left) and download of all the file jobs (right) the middle gradient colored button allows users to download the PDB with SASA values
