By pressurising enzyme crystals with gas and collecting X-ray data, researchers have mapped the routes CO₂ takes as it travels through the protein, revealing a 'waiting room' where substrate molecules queue up just outside the catalytic centre before being processed. www.esrf.fr/home/news/sp...

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.
