Comparative Structural Analysis of Escherichia Coli Cyay at Room and Cryogenic Temperatures Using Macromolecular and Serial Crystallography

open access: yesChemBioChem, Volume 26, Issue 20, October 31, 2025.
Room‐temperature (RT) crystallography of E. coli CyaY, the bacterial frataxin homolog, reveals subtle but functionally relevant differences from cryogenic structures. The conserved fold shows distinct side‐chain conformations and water networks, highlighting dynamics often hidden at low temperatures.
