Likewise, it was great! Could only be there for a couple of days, unfortunately...Hoping Boston has more metalloproteins :)

Last day at #discoverbmb2026 #asbmb2026
@asbmb.bsky.social ! My lab and all of the UMBC-UMB T32 CBI students had a blast! Looking forward to Boston next year!

While I haven't been able to be at the whole meeting, I've been heartened and reinvigorated by the spirit of all of the great science so far at #discoverbmb2026 #asbmb2026 @asbmb.bsky.social ! Plus, look at all those great UMBC T32 CBI trainees networking and sharing their science. Inspirational!

Love a good 4(Cys) Fe-binding site :D

Well-deserved!!

Co-translational control of protein stability and quality in plants Abstract. Proteostasis relies on the coordinated control of protein synthesis, folding, modification and degradation, and an increasingly clear picture is

My review “Co-translational control of protein stability and quality in plants” is now online at @jxbotany.bsky.social, in which I describe how co-translational processing and ribosome-associated quality control together establish protein stability and fate early in synthesis. tinyurl.com/5dhhz9h6

X-ray beam effects on metallo-peptides reflect redox events: insights from X-ray absorption spectroscopy measurements on metal complexes of truncated amyloid-β peptides X-ray exposure influences the structures of Cu(I), Cu(II) and Zn(II) complexes of amyloid-β (Aβ) peptides in different ways. While Cu(I) and Zn(II) complexes show no detectable X-ray-induced spectral changes, Cu(II) complexes undergo significant spectral evolution under irradiation. Experiments on the truncated fragments Aβ1–6 and Aβ1–16 show that the extent of relaxation depends on the peptide length, on the binding mode and on the temperature.

The structure of the full catalytic cycle of Vibrio cholerae NFeoB The acquisition of iron is critical for the survival and the virulence of numerous infectious pathogens, and most bacteria acquire ferrous iron (Fe2+)…

🚨 Just in press @jmolbiol.bsky.social 🚨 Kate, Candice, and Mark's paper on the structure of the V. cholerae NFeoB NTPase catalytic cycle. Serendipity of a P1 spacegroup with 4 mols in the ASU played a role in capturing all the states, and Mg is pivotal! Read the paper here: tinyurl.com/mr3dmmjz

🚨New paper: We found - contrary to expectations - that oxygen is partially excluded from biomolecular condensates.

We find a strong anti-correlation between oxygen and protein concentrations in the condensate showing that accessible volume dominates over polarity.

Science is still correct even if you don’t believe in it…

In vitro reconstitution in membrane environment reveals critical lipid dependence of substrate S-acylation by protein palmitoyltransferase enzymes Protein S-acylation, also known as protein palmitoylation, is a common form of post-translational modification and the most abundant form of lipid modification of proteins with several thousands of su...

New paper from our lab !
Thousands of proteins are targets of a form of post translational lipid attachment known as protein S-acylation, commonly as protein palmitoylation. 23 transmembrane zDHHC enzymes catalyze protein S-acylation in humans.

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.
