Revealing the hidden world of shape shifting enzymes using Cryo-EM. Senior research associate at Newcastle University, UK. Currently working as part of Recon4IMD https://www.recon4imd.org Views are my own.
I am excited to share our new preprint on our structural and biochemical analyses of human methionine synthase (MTR). This was the hard work of Douglas Ferreira who carried out this research as a significant part of his PhD. #CryoEM www.biorxiv.org/content/10.1...
Structural insights into cobalamin loading and reactivation of human methionine synthase
Human methionine synthase (MTR) is an essential enzyme of one carbon metabolism. Consisting of a catalytic N-half and a cobalamin binding C-half, MTR utilises this intricate organometallic cofactor in...

The number of low-quality or fraudulent publications is rising to hundreds of thousands per year. It is time to reevaluate current publishing models and outline a global plan. Read the 'Reformation of science publishing: the Stockholm Declaration': royalsocietypublishing.org/doi/10.1098/... #RSOS 🧪

Using Leishmania as a model, we determined the cryo-EM structure of the doublet microtubule to pinpoint the position of each dynein. This gave us a detailed map of where every “rower” sits on the ciliary “boat.”

... a sharp image on a piece of film.
What it revealed was this: fuzzy edges with four distinct "spots" in an X pattern in the interior.
This was compared to the chemical structures worked out for the nucleotides themselves, suggesting a stacked pattern of interacting bases.

As far as I understand leads me to ask why merge the same micelle density twice into a map? This is an unusual map of a cytosolic protein embedded in the membrane of a liposome. There is no explanation for how this map was derived in the associated paper. www.ebi.ac.uk/emdb/EMD-47001

Happy to share our @narjournal.bsky.social paper on the mechanism of Dmc1 filament stabilization by Mei5-Sae3!
We show that Mei5-Sae3 can stabilize both active and inactive Dmc1 filaments, and that this is independent of the ATP hydrolytic cycle.

Mei5–Sae3 stabilizes both active and inactive forms of Dmc1 filaments independently of its impact on ATP hydrolysis
Abstract. In budding yeast, Dmc1’s recombinogenic activity is controlled by the meiosis-specific heterodimer Mei5–Sae3. Mei5–Sae3 is required for assembly

ICYMI: New online: Architecture of the human KICSTOR and GATOR1–KICSTOR complexes
Architecture of the human KICSTOR and GATOR1–KICSTOR complexes
Nature Structural & Molecular Biology, Published online: 06 November 2025; doi:10.1038/s41594-025-01693-4Teng and Zeng et al. use cryo-electron microscopy to show that the crescent scaffold of KICSTOR anchors GATOR1 to lysosomes and disruption of the interaction causes mTORC1 hyperactivation and TFE3 mislocalization. KICSTOR enables nutrient-dependent mTORC1 regulation by binding anionic lipids for lysosomal targeting.

As James Watson dies, let's remember Rosalind Franklin's contribution to the discovery of DNA.
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.
