TTHA0988 from T. thermophilus represents a class of protein found almost ubiquitously across bacterial species which is incorrectly annotated as allophanate hydrolase. Three crystal forms of TTHA0988 have been solved which reveal the domain organization and range of motion within this protein family.

X-ray crystal structures of the cyclosporin A analogue E-ISA247 (voclosporin) and its stereoisomer Z-ISA247 bound to cyclophilin A suggest the molecular basis for the differences in their binding affinities and immunosuppressive efficacies.

The crystal structure of the trypsin–bovine pancreatic trypsin inhibitor (BPTI) complex was refined using X-ray and neutron data. Both protonation states of the catalytic triad and H/D exchange of the amide H atom of P1′ Ala16 of the scissile peptide bond were observed in the trypsin–BPTI complex.
