K-edge-based interior tomography.
Oh O, Lee SW, Wang G. Oh O, et al. Phys Med Biol. 2018 Aug 22;63(16):165017. doi: 10.1088/1361-6560/aad707. Phys Med Biol. 2018. PMID: 30063032
Interior tomography reconstructs a region of interest using truncated projection data, but it is subject to the ill-posedness of interior tomography. With the photon-counting detector, K-edge imaging uses data in the low and high energy bins around the K-edge of a c …

Evaluating the impact of X-ray damage on conformational heterogeneity in room-temperature (277 K) and cryo-cooled protein crystals.
Yabukarski F, Doukov T, Mokhtari DA, Du S, Herschlag D. Yabukarski F, et al. Acta Crystallogr D Struct Biol. 2022 Aug 1;78(Pt 8):945-963. doi: 10.1107/S2059798322005939. Epub 2022 Jul 14. Acta Crystallogr D Struct Biol. 2022. PMID: 35916220 Free PMC article.
Nevertheless, high sensitivity to X-ray damage at RT raises concerns about data reliability. To systematically address this critical issue, increasingly X-ray-damaged high-resolution data sets (1.02-1.52 A resolution) were obtained from single proteinase K, t …

Sequential substitution of K(+) bound to Na(+),K(+)-ATPase visualized by X-ray crystallography.
Ogawa H, Cornelius F, Hirata A, Toyoshima C. Ogawa H, et al. Nat Commun. 2015 Aug 10;6:8004. doi: 10.1038/ncomms9004. Nat Commun. 2015. PMID: 26258479 Free PMC article.
Na(+),K(+)-ATPase transfers three Na(+) from the cytoplasm into the extracellular medium and two K(+) in the opposite direction per ATP hydrolysed. The binding and release of Na(+) and K(+) are all thought to occur sequentially. Here we demonstrate by X-ra …
