High-temperature and high-resolution crystallography of thermostable copper nitrite reductase†
Abstract
The 1.55 Å resolution thermostable copper nitrite reductase structure at 320 K displayed a near-bidentate binding mode of nitrite distinct from a monodentate mode in a cryogenic structure. To our knowledge, this is the first case in which the difference in substrate binding modes between cryogenic and high-temperature structures has been visualized by crystallography.
