abstract = {The vast majority of protein structures are determined at
cryogenic temperatures, which are far from physiological
conditions. Nevertheless, it is well established that
temperature is an essential thermodynamic parameter for
understanding the conformational dynamics and functionality
of proteins in their native environments. Time-resolved
crystallography is a technique that aims to elucidate
protein function by examining structural alterations during
processes such as ligand binding, catalysis, or allostery.
However, this approach is typically conducted under ambient
conditions, which may obscure crucial conformational states,
that are only visible at physiological temperatures. In this
study, we directly address the interplay between protein
structure and activity via a method that enables
multi-temperature, time-resolved serial crystallography
experiments in a temperature window from below 10 °C to
above 70 °C. Via this 5D-SSX, time-resolved experiments
can now be carried out at physiological temperatures and
with long time delays, providing insights into protein
function and enzyme catalysis. Our findings demonstrate the
temperature-dependent modulation of turnover kinetics for
the mesophilic β-lactamase CTX-M-14 and the thermophilic
enzyme xylose isomerase, within the full protein structure.},
