research papersCoarse snapshots of oxygen-dissociation intermediates of a giant hemoglobin elucidated by determining the oxygen saturation in individual subunits in the crystalline state
Crystal structures of oxy-deoxy intermediates of a 400 kDa giant hemoglobin reveal the allosteric transition intermediates of the unmodified protein and unrestrained oxygen saturation, which have been missing pieces in the study of the allosteric behavior of hemoglobins over the last half a century.
research papersresearch papersMolecular basis of dimerization of lytic transglycosylase revealed by the crystal structure of MltA from Acinetobacter baumannii
MltA from the human pathogen Acinetobacter baumannii was characterized and its dimeric crystal structure was unveiled, demonstrating the extra-domain-mediated dimerization of MltA for the first time. Based on the current structural and biochemical studies, the working mechanism of MltA with various functionally related proteins on the bacterial outer membrane was modeled.
research papersCryo-TEM simulations of amorphous radiation-sensitive samples using multislice wave propagation
This work describes cryo-TEM simulations of amorphous radiation-sensitive samples using multislice wave propagation by introducing the `frozen plasmon' method. Combined with a coarse-grained all-atom solvent model accurately models inelastic scattering effects like radiation damage, solvent motion and contrast loss.
research papersLocating hydrogen positions in the autunite mineral metatorbernite [Cu(UO2)2(PO4)2·8H2O]: a combined approach using neutron powder diffraction and computational modelling
A combination of neutron powder diffraction and ab initio random structure searching was used to locate hydrogen positions in the crystal structure of metatorbernite [Cu(UO2)2(PO4)2·8H2O], a common autunite mineral that shows promise for uranium remediation.
research papersPink-beam serial femtosecond crystallography for accurate structure-factor determination at an X-ray free-electron laser
Large-bandwidth X-ray free-electron laser pulses significantly reduce sample and beam-time quantities required for obtaining accurate structure-factor amplitudes in serial femtosecond crystallography.
