Forthcoming article in Acta Crystallographica Section D Structural Biology



Acta Crystallographica Section D: Structural Biology welcomes the submission of articles covering any aspect of structural biology, with a particular emphasis on the structures of biological macromolecules and the methods used to determine them. Reports o



 



Structural insights into the interaction of the conserved mammalian proteins GAPR-1 and Beclin 1, a key autophagy protein
A pentad mutation of GAPR-1 causes structural changes, and shifts the GAPR-1 monomer-dimer equilibrium toward dimerization, which together may prevent its binding to Beclin 1.



2017 publication guidelines for structural modelling of small-angle scattering data from biomolecules in solution: an update
Updated guidelines are presented for publishing biomolecular small-angle scattering (SAS) experiments so that readers can independently assess the quality of the data and models presented. The focus is on solution scattering experiments with either X-rays (SAXS) or neutrons (SANS), where the primary goal is the generation and testing of three-dimensional models, particularly in the context of integrative/hybrid structural modelling.



Designing better diffracting crystals of biotin carboxyl carrier protein from Pyrococcus horikoshii by a mutation based on the crystal-packing propensity of amino acids
In order to improve the efficiency of protein crystallization, an alternative approach using the mutation of surface residues was devised based on the results of statistical analysis of the crystal-packing propensity of amino acids. A systematic crystallization experiment validated the results of the statistical analysis.



Crystal structures of the methyltransferase and helicase from Zika virus strain MR766
High-resolution structures of the Zika virus strain MR766 methyltransferase and helicase proteins are reported.



The structure of the Pfp1 protease from the hyperthermophilic archaeon Thermococcus thioreducens in two crystal forms
The structure of the Pfp1 intracellular protease from T. thioreducens was solved in two crystal forms: one showing it to be a hexamer and the other a dodecamer. The subunits are disulfide-linked in pairs and the very closely juxtaposed catalytic triads are formed across an interface with amino acids contributed by two separate subunits.



Protein structure determination by electron diffraction using a single three-dimensional nanocrystal
A single three-dimensional protein nanocrystal was used for structure determination by electron diffraction. Data were acquired using the rotation method with a Timepix hybrid pixel detector for low-dose data acquisition.



Model validation: local diagnosis, correction and when to quit
An overview of current crystallographic model validation of protein and RNA, both foundations and criteria, at all resolution ranges is provided, together with advice on how to correct specific types of problems and on when one should not try so hard that one is overfitting.



AUSPEX: a graphical tool for X-ray diffraction data analysis
AUSPEX is a new software tool for the statistical analysis of single-crystal X-ray diffraction data. It can be used to identify problems in the data resulting from the experiment itself, image processing, data scaling or conversion.
