Structural insights into urocanate reductase using room‐temperature X‐ray crystallography
Acta Crystallographica Section D, Volume 82, Issue 6, Page 603-614, June 2026.The active‐site dynamics of the microbial enzyme urocanate reductase were revealed by room‐temperature X‐ray crystallography.Urocanate reductase (UrdA) is a bacterial enzyme that converts urocanic acid to imidazole propionate. Its catalytic residue Arg411 undergoes a large conformational change in the substrate‐bound versus product‐bound states.
