Protein-ligand complex structure from serial femtosecond crystallography using soaked thermolysin microcrystals and comparison with structures from synchrotron radiation

Toward the pharmaceutical application of the X-ray free-electron laser, the applicability of ligand soaking method in the serial femtosecond crystallography has been examined.

Toscana virus nucleoprotein oligomer organization observed in solution

The nucleoprotein of Toscana virus forms mainly open fivefold oligomers consistent with the encapsidation mechanism of the phlebovirus RNA both in solution and under physiological conditions.

Role of conserved surface hydrophobic residues in the carbapenemase activity of the class D β-lactamases

The crystal structure of the class D carbapenemase OXA-143 from A. baumannii shows that a conserved valine residue on the protein surface controls access of the deacylating water molecule to the active site of the enzyme. Analysis of the structures of other class D carbapenemases implicates movement of juxtaposed surface valine and leucine residues in a universal deacylation mechanism for these enzymes.
