Bogeun Kim et al.: First crystal structure of the DUF2436 domain of virulence proteins from Porphyromonas gingivalis #DUF2436Domain #OralPathogen #PorphyromonasGingivalis #IUCr https://journals.iucr.org/paper?S2053230X24008185
The DUF2436 domain of unknown function is highly conserved in virulence proteins from the pathogenic oral bacterium P. gingivalis. Theis domain exhibits a noncanonical β-jelly-roll sandwich topology with a previously unobserved fold consisting of two antiparallel β-sheets and one short α-helix.
Kennedy et al.: Introducing the Best practice in crystallography series #BestPractice #Crystallography #IUCr https://journals.iucr.org/paper?S2053229624009331
The first three articles of the new `Best practice in crystallography' series have been published covering a guide to growing crystals for single-crystal diffraction studies, a guide to performing photocrystallography and a review detailing what aspects of crystal structure are of particular importance to determining electrical conductance in organic materials.

Vasyl Ryukhtin et al.: Pinhole small-angle neutron scattering based approach for desmearing slit ultra-small-angle neutron scattering data #SmallAngleNeutronScattering #USANS #Desmearing #IUCr https://journals.iucr.org/paper?S1600576724008380
This study presents a new, methodologically robust approach for accurately desmearing slit-smeared ultra-small-angle neutron scattering (USANS) data. The proposed technique, validated on porous anodized aluminium oxide membranes, facilitates the precise merging of USANS and small-angle neutron scattering data, offering improved data analysis capabilities in the mesoscale structural research domain.
