I'm proud to present this first article from my PostDoc: We probed the different responses of metalloproteins (myoglobin, Mb and a copper-containing Nitrite Reductase, CuNIR) to reduction of their metal centres by X-rays at two temperatures (100K, 392K-RT) with UV-vis absorption and diffraction.

Intense, ultrashort X-ray pulses have been used to probe the extraordinary reactions that occur in a light-sensing receptor, resolving a biochemical conundrum go.nature.com/4tidDwm

CryoRhodopsins: A comprehensive characterization of a group of microbial rhodopsins from cold environments www.science.org/doi/10.1126/...

EMBL Hamburg scientists have discovered a group of microbial cold-loving molecules, ‘cryorhodopsins’, with extraordinary abilities. They are the first observed molecules that can act as both on and off switches for electrical activity in cells. www.embl.org/news/science...

Excited that our article made the cover of the July issue of @actacrystf.iucr.org! Congrats to my coauthors @gabbygrowsxtals.bsky.social & Vivian Stojanoff! Grateful for #NIH NIGMS R24 National Resource grant that enables workshops like the 2023 SAMPREP workshop @ @acastructuralsci.bsky.social
