Elucidation of the mechanism of interaction between Klebsiella pneumoniae pullulanase and cyclodextrin

Crystal structures of K. pneumoniae pullulanase (KPP) in complex with α-, β- or γ-cyclodextrin were determined at around 1.98–2.59 Å resolution. Cyclodextrins interact with CBM41 and the active site of KPP. In the active site, Phe746 interacts with the inner cavity of the cyclodextrin rings. The strong inhibition of KPP by β-cyclodextrin is caused by the optimized interaction between β-cyclodextrin and the side chain of Phe746. These structures and the kinetic parameters of recombinant pullulanase and the F746A variant revealed the importance of Phe746 in the selective binding of cyclodextrins.

Improving the accuracy and resolution of neutron crystallographic data by three-dimensional profile fitting of Bragg peaks in reciprocal space

It is demonstrated that using three-dimensional profile fitting of Bragg peaks increases the accuracy and resolution of neutron crystallographic data collected from proteins and reveals new features in nuclear density maps calculated from these data.

Structures of two fimbrial adhesins, AtfE and UcaD, from the uropathogen Proteus mirabilis

The crystal structures of two fimbrial adhesins from the uropathogen P. mirabilis are reported as a first step towards unveiling their role in pathogenesis. Despite lacking significant sequence homology, the two structures are very similar.

Status of the neutron time-of-flight single-crystal diffraction data-processing software STARGazer

In this article, the status of the STARGazer data-processing software and its data-processing algorithms are described in detail. The STARGazer data-processing software is used for neutron time-of-flight single-crystal diffraction data collected using the IBARAKI Biological Crystal Diffractometer.

Structure of VDAC-tethered bilayer lipid membranes determined using neutron reflectivity

Using neutron reflectivity, we provide a comprehensive structural characterization of each step in the formation of a protein-tethered bilayer lipid membrane. We report relevant physical parameters of self-assembled monolayers, surface-captured detergent-stabilized protein, and the bilayer lipid membrane reconstituted by dialysis around the surface-captured tethering proteins.

Resolving polymorphs and radiation-driven effects in microcrystals using fixed-target serial synchrotron crystallography

Multiple dose-dependent room-temperature structures of copper nitrite reductase were determined from microcrystals in a single silicon nitride fixed-target chip. The separation of crystal polymorphs into distinct structures is described, together with the characterization of X-ray-irradiation effects through the dose series.
