#glycotime🧵
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?

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

Lectins are known to be low affinity binders with relatively broad glycan target preference. In this work live in @commsbio.nature.com we show how Siglecs change this paradigm, acting as molecular precision tools required to fine tune immune response 🤯 #glycotime 🧵⬇️

Glycolipid recognition and binding by Siglec-6 hinges on interactions with the cell membrane - Communications Biology
Siglecs are immunoregulatory lectins with very similar architectures. The authors show how the V-set domain of Siglec-6 allows it to select for precise sialylation patterns in specific biological envi...

Happy birthday to us! 🥂🎂🥳 We are only 2 yo, but so much #glycotime happened since Dec 2023! ⬇️🧵

We truly appreciate your support, you fabulous glycoengineers around the world and we have so many exciting new tools for you coming up in 2026 to make your 3D glycoforms even better and faster! 🤩

Tuesday #glycotime 🥄🍬

Glycans are a 🔝 example of "disordered" molecules. Inherent flexibility prevents sugars from adopting fixed, unique 3D positions relative to the crystal lattice, so they often are invisible to X-ray diffraction, unless they are bound and thus restrained in place 1/3 🧵

Wee thread 🧵⬇️ on our new #glycotime with @siglecdude.bsky.social John Klassen and @glycocode.bsky.social 🥳 where we show Siglecs as molecular precision tools, able to recognise sialylated glycans with surgical precision in their natural environment, not bad for a lectin! 😎

doi.org/10.1038/s420...
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 😎

Three part #glycotime🧵⤵️ if you want to know more about a very unique, rare but previous type of glycosylation: C-mannosylation

One of my favourites 💚 (because it is a very special mannose 😁)
For some unique #glycotime: C-man is a rare (but evolutionarily very old[1]) post translational modification of proteins, where the C2 of Trp in W-x-x-W/C sequons are linked to a single man through a C-C bond 🤯 This and its position within the structure stabilises the (unusual for man) 1C4 chair[2]

When glycan recognition is linked to immune response, you need fine tuning! 😎

Here ⬇️ we show how human Siglecs act as molecular precision tools, recognising the glycan and also the biological environment (or context) these glycans are found in. A 1/5 #glycotime🧵 ⬇️

Do you think 🪰 can only do stubby (and boring) oligoman-type N-glycans? Think *again* 🤯

This fabulous #glycotime work ⬇️ led by the N-glycan extraordinaire @iainwilsonwien.bsky.social, shows that different sf9 and high five cells produce VERY fancy glycans 1/3 🧵

Picture this: your fav protein-protein interaction is *entirely* dependent on,
1) glycans 💥
2) the type of glycans 🤯💜
