Real-time nuclear magnetic resonance spectroscopy in the study of biomolecular kinetics and dynamics
Magnetic Resonance(2021)
摘要
Abstract. The review describes the application of nuclear magnetic resonance (NMR) spectroscopy to study kinetics of folding, refolding and aggregation of proteins, RNA and
DNA. Time-resolved NMR experiments can be conducted in a reversible or an
irreversible manner. In particular, irreversible folding experiments pose large requirements for (i) signal-to-noise due to the time limitations
and (ii) synchronising of the refolding steps. Thus, this contribution discusses the application of methods for signal-to-noise increases, including dynamic nuclear polarisation, hyperpolarisation and photo-CIDNP for the
study of time-resolved NMR studies. Further, methods are reviewed ranging
from pressure and temperature jump, light induction to rapid mixing to induce rapidly non-equilibrium conditions required to initiate folding.
