Structure of the D140N mutant of chitinase B from Serratia marcescens at 1.45 Å resolution

The refined high-resolution structure of the D140N mutant of chitinase B from S. marcescens sheds light on the roles of Asp140 and Asp142 during catalysis.

Structure of the photoactive yellow protein reconstituted with caffeic acid at 1.16 Å resolution

The crystal structure of photoactive yellow protein with a modified chromophore shows the chromophore to be bound in two different conformations. From this crystallographic study and spectroscopic studies, caffeic acid binds the protein in a strained conformation.
