The highest resolution structure of bacterial type II NADH:quinone oxidoreductase was determined at 2.15 Å resolution. This structure was used for in silico quinone substrate-docking studies to investigate the binding poses of menadione and ubiquinone molecules.

Structural information on the 607-amino-acid human ATG16L1 protein is restricted to the N-terminal ATG5-binding domain and the recently reported structure of the C-terminal WD40 domain, whereas structural information for the central region of ATG16L1 remains elusive. In this work, the identification, purification, biochemical characterization and crystallization of a stable ATG16L1 subfragment comprising residues 72–307, comprising the so far structurally uncharacterized central region of ATG16L1, are presented.

Virus-like particles (VLPs) from Norovirus Chiba strain were crystallized and data were collected to 3.2 Å resolution. X-ray analysis revealed that although 38 nm VLPs with T = 3 symmetry had been prepared for crystallization, the crystal contained 23 nm VLPs with T = 1 icosahedral symmetry.
