Critical evaluation of three cryo‐EM structures of particulate methane monooxygenase by quantum refinement

open access: yesActa Crystallographica Section D, EarlyView.
We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites

Explicit correction of severely non‐uniform distributions of cryo‐EM views

open access: yesActa Crystallographica Section D, EarlyView.
An explicit numerical leveling of non‐uniformly distributed sets of 2D projections with the program VUE improves the 3D reconstructions and illustrates sources of image distortion.The quality of three‐dimensional macromolecular image reconstruction by cryo electron microscopy (cryo‐EM) strongly depends on the number and the quality of the respective ...

Addressing ecological challenges from a quantum computing perspective

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract With increased access to data and the advent of computers, the use of statistical tools and numerical simulations is becoming commonplace for ecologists. These approaches help improve our understanding of ecological phenomena and their underlying mechanisms in increasingly complex environments.
