The first crystal structure of manganese superoxide dismutase from the genus Staphylococcus

This paper is the first to describe the crystal structure of manganese superoxide dismutase from the genus Staphylococcus in recombinant S. equorum MnSOD Asp13Arg. Its amino-acid sequence is highly similar to that of B. subtilis MnSOD and therefore its three-dimensional structure is presumably also similar, with only slight changes. S. equorum and B. subtilis MnSODs display different thermal and chemical stability. The slightly different structure of S. equorum MnSOD may provide an explanation for the differences in stability.

High-resolution structure of the influenza A PB2cap binding domain illuminates the changes induced by ligand binding

A crystallographic structure of native influenza A PB2cap was solved to 1.52 Å resolution. B-factor difference plots and r.m.s.d. plots among known structures suggest functionally relevant disassociation of the N-terminal ligand-binding domain from the C-terminal domain.

Xylanase B from Clostridium cellulovorans 743B: overexpression, purification, crystallization and X-ray diffraction analysis

The overexpression, purification, crystallization and X-ray diffraction analysis of xylanase B from C. cellulovorans 743B were performed.

A thermostable and alkaline GDSL-motif esterase from Bacillus sp. K91: crystallization and X-ray crystallographic analysis

Purification, crystallization and X-ray crystallographic analysis were employed to determine the catalytic mechanism of Est8, a GDSL-motif esterase from Bacillus sp. K91.

Structural characterization of Porphyromonas gingivalis enoyl-ACP reductase II (FabK)

The structure of P. gingivalis enoyl-ACP reductase II (FabK) was determined via X-ray crystallography to 1.9 Å resolution with all flexible loops visible, FMN fully resolved and the NADPH cofactor partially resolved. Characterization includes the structural basis of NADPH dependence and the role of a required monovalent cation.

Structure of a Talaromyces pinophilus GH62 arabino­furanosidase in complex with AraDNJ at 1.25 Å resolution

The three-dimensional structure of a fungal arabinofuranosidase from CAZY family GH62 has been solved at 1.25 Å resolution in complex with the bespoke arabinofuranosidase inhibitor AraDNJ, shedding light on the activity of this catalyst in the enzymatic deconstruction of arabinoxylans.

Accepted 2 January 2018

Ribokinase from Leishmania donovani: purification, characterization and X-ray crystallographic analysis

Ribokinase from L. donovani was cloned, purified, characterized and crystallized, and data were collected to a resolution of 1.95 Å. X-ray crystallographic analysis showed the presence of two molecules in the asymmetric unit, and human ribokinase was used as a template to determine the three-dimensional structure.

Human CCL5 trimer: expression, purification and initial crystallographic studies

In order to study the oligomeric structure of human CCL5, a new strategy to prepare the CCL5 trimer was developed and a crystal was obtained that diffracted to a satisfactory resolution of 1.87 Å.

Accepted 30 December 2017

X-ray crystallographic and high-speed AFM studies of peroxiredoxin 1 from Chlamydomonas reinhardtii

The oligomeric state of the 2-Cys peroxiredoxin from the green alga C. reinhardtii was determined by an X-ray crystallographic study and high-speed AFM image analysis.

Structure of bovine cytochrome c oxidase in the ligand-free reduced state at neutral pH

Although the enzymatic activity of cytochrome c oxidase (CcO) depends sensitively on pH over a wide range, X-ray structural analyses of bovine CcO have been conducted using crystals prepared at pH 5.7 owing to the difficulty in crystallizing this protein. Here, the structure of ligand-free reduced CcO was successfully determined at 1.99 Å resolution.

Accepted 24 December 2017

The Pex4p–Pex22p complex from Hansenula polymorpha: biophysical analysis, crystallization and X-ray diffraction characterization

The biophysical characterization and crystallization of the Pex4–Pex22 complex from H. polymorpha are reported.
