Finally, a detailed review about C-mannosylation: mechanism of C-mannosyltransferases and the influence of the C-mannosylation on the function of several proteins. Highly recommended to everyone in this type of post-translational modification! tinyurl.com/3ywjmfk3 #glycotime

Just a reminder that when the Nazis were marching in to Copenhagen, Neils Bohr chose to dissolve his medal rather than have any Nazi take possession of it.

Authors use “Siglec-7 and -15…Fc chimera to demonstrate that CHST1-mediated 6-O-sulfation markedly enhanced binding to select O-glycoproteins, namely MAdCAM1, CD43, and PSGL-1” www.biorxiv.org/content/10.6...

The robots are not coming for your jobs, but bullshitters with robots ARE competing for your jobs, and unless we decouple publishing metrics from career paths (financial gain), we are going to lose both careers and our capacity to share information. doi.org/10.1126/science.adw3000

There are so many quotes in this article that read as dystopian satire - but the worst has to be the overall idea that the one thing conservation efforts need is the Silicon Valley treatment. Pauli’s phrasing of “not even wrong” seems very apt here.

🚨 Are you into comp chem/biophys? Do you like glycobiology? Are you located around Freiburg Germany? Do you like me as a person? Want to see an open lecture about Computational Glycobiology/Biophysics in Freiburg, Germany, delivered by me?! 15 Dec, 17:15 HS Chemie @ Alberstrasse 21, 79104 Freiburg

We are looking for a motivated PhD student to join our lab! #SPPL3 #glycotime #Golgi #UniKiel

Last stretch for these positions, as the deadline for this is on Sunday!

Hey @biorxivpreprint.bsky.social @altmetric.com , I haven’t been able to see the BlueSky metrics for preprints for a while now on the BioRxiv website, so I am missing out on all the salacious gossip about the preprints. Is this a known bug?

Another bump for the postdoc and PhD positions still open at the center and postdoc specifically within my group (same link to apply). We’re looking for wet/dry lab, and I’m specifically after people who do magic with computers!

Reminder: our postdoc and PhD positions are still open. We work across different areas (wet and dry lab), but I am especially after people with a computational biology, bioinformatics, pytorch whisperer kind of background. Protein design and OpenFold/AF also counts.

Pretty low-effort example of plagiarism here.

I have a PhD position available in my lab at the University of Freiburg!! If you, or someone you know, might be looking for a position using modeling and simulations to uncover secrets in (glyco-)protein structure/function relationships please take a look at our website! www.kearnslab.org

It’s cool to see more stuff being built on top of Joshua Klein’s mzdata libraries. I’ve been playing around with a version that compiles down to WASM, which has been great to work with.

We all agree that LinkedIn is absolutely awful, right? Every other click on there is some highly optimised funnel to extract money from you. Hard to believe that people think it’s a good network for “science” discussions.

Also, on top of the postdoc and PhD positions open, you should also get in touch if you would like to try your hand at an EMBO or Marie Curie fellowship with us to get a headstart on your independent career.

It is awesome that this work keeps going on. No idea where it’s going, but it looks fun!

Vaguely remember differences in glycosylation for spike alone vs native virus, and another paper that implicated N in slowing Golgi transit. Anyone with a better memory than me remember the refs? No doubt that viral protein effects on endomembranes are complex and overlapping.

This is a cool dive into AF3, with a really nice way to get AF3 to do something much more closely matching reality.

This might be be a dumb question, but do we know which glycans end up on the surfaces here after GGTA1/B4GALNT2/neuGc knockouts? Would obviously guess we miss these epitopes, but are they truncated, or replaced with some other epitope (apart from the obvious NeuAc)? www.nature.com/articles/s41...

Sad, but probably inevitable news from Vodafone AU. I have been sitting on an ancient mobile phone plan for the past 25 years, with no minimum cost for infrequent usage, and they’re finally removing the plan. Are there any reputable places to port Australian mobile numbers to for e.g., VOIP?

If anyone is keen on testing the reglycosylation plugin for PyMOL, please get in touch! There’s a few rough edges I’d like to iron out, and would appreciate feedback.

This Lorenz Oken guy might just be on to something. The article mixes slime and mucus interchangeably, but it is a good read about the relative rarity of complex life. www.asimov.press/p/slime

Well, it turns out that you can actually make PyMOL do quite a lot of stuff. Here's the full workflow, integrating the amazing ReGlyco into PyMOL to re-glycosylate the LDLA linker. There's some serious magic needed to get it running as fast as it is within PyMOL. @elisafadda.bsky.social

Interesting thread below! One thing I have been trying to understand is how NNs can store so much info in such a relatively “small” parameter space, such that the concepts are stored in the “direction” in a latent space. This idea would fit nicely with this model.

Looks intriguing! granta.com/slime/

This looks like a great resource to gain a conceptual understanding of deep learning models. It would be amazing to have a “Design Patterns” style book a la Gang of Four, just with patterns to detect, and the method to train it.

A little bit of glycan binding structure for your Tuesday.

Obviously, bad. But doubly so because I would actually be really interested in seeing a galectin / Tim-3 interaction structure!

Looks like great stuff from Martin & co in thread this comment is on - but the comment highlights what could be most interesting here. Is this hinting (natural) protein space is bounded, and so if you can’t find function in extant proteins, maybe proteins simply can’t do it?

Putting together teaching material for a Medical Data Understanding course, and while looking up early medical informatics, I found out about this absolute legend. Apart from initiating what is now MEDLINE (Index Medicus), he also had an assistant, Hollerith…

I have this script I use to munge citations in word docs, that spelunks into the XML and creates Zotero/Mendeley compatible field codes. I figured it couldn’t be that hard to get it working for EndNote. It was. Even Gemini told me not to, which made me even more determined. Now it works.

And here the question: are they both active? which one is the responsible for the GalT activity? We combined #mutagenesis with #biophysics and #moleculardynamics to show that only the GT2 domain exhibits catalytic activity, facilitated by an unusual Glu-Asp-Asp motif critical for Mn²⁺ binding.

Super happy to share the final shape of our work describing the molecular #structure and #enzymatic mechanism of human #collagen #galactosyltransferase #GLT25D1 published in @natcomms.nature.com. Want to know how collagen become sweet? read the 🧵 below!

It’s not my day-job to look after HomeAssistant, but as allergy season is kicking in, I thought I should update our dashboard for allergens. This time, I tried using Aider + Gemini Pro 2.5 to do the update. Unbelievably cool workflow with reasonable code generated. github.com/hirenj/Polle...
