Enzyme transient state kinetics in crystal and solution from the perspective of a time-resolved crystallographer
With recent technological advances at synchrotrons [Graber et al., J. Synchrotron Radiat. 18, 658–670 (2011)], it is feasible to rapidly collect time-resolved crystallographic data at multiple temperature settings [Schmidt et al., Acta Crystallogr. D 69, 2534–2542 (20...

description |
With recent technological advances at synchrotrons [Graber et al., J.
Synchrotron Radiat. 18, 658–670 (2011)], it is feasible to rapidly collect
time-resolved crystallographic data at multiple temperature settings [Schmidt et
al., Acta Crystallogr. D 69, 2534–2542 (2013)], from which
barriers of activation can be extracted. With the advent of fourth generation X-ray
sources, new opportunities emerge to investigate structure and dynamics of biological
macromolecules in real time [M. Schmidt, Adv. Condens. Matter Phys. 2013,
1–10] in crystals and potentially from single molecules in random orientation in solution
[Poon et al., Adv. Condens. Matter Phys. 2013, 750371].
Kinetic data from time-resolved experiments on short time-scales must be interpreted in
terms of chemical kinetics [Steinfeld et al., Chemical Kinetics
and Dynamics, 2nd ed. (Prentience Hall, 1985)] and tied to
existing time-resolved experiments on longer time-scales [Schmidt et al.,
Acta Crystallogr. D 69, 2534–2542 (2013); Jung et al., Nat.
Chem. 5, 212–220 (2013)]. With this article, we will review and outline steps
that are required to routinely determine the energetics of reactions in
biomolecules in crystal and solution with newest X-ray sources. In eight sections, we aim
to describe concepts and experimental details that may help to inspire new approaches to
collect and interpret these data. |
