Anomalous signal from S atoms in protein crystallographic data from an X-ray free-electron laser

Analysis of serial femtosecond crystallographic data measured using the SACLA free-electron laser at RIKEN Harima shows the weak anomalous signal from naturally occurring S atoms in a protein.

Structures of the catalytic EAL domain of the Escherichia coli direct oxygen sensor

Structures of the EAL domain of the E. coli direct oxygen sensor show the active site in a nonproductive conformation that has implications for the regulatory mechanism.

Combining crystallography and EPR: crystal and solution structures of the multidomain cochaperone DnaJ

The crystal structure of the N-terminal part of T. thermophilus DnaJ unexpectedly showed an ordered GF domain and guided the design of a construct enabling the first structure determination of a complete DnaJ cochaperone molecule. By combining the crystal structures with spin-labelling EPR and cross-linking in solution, a dynamic view of this flexible molecule was developed.
