abstract = {We use a hybrid fluorescence spectroscopic toolkit to
monitor T4 Lysozyme (T4L) in action by unraveling the
kinetic and dynamic interplay of the conformational states.
In particular, by combining single-molecule and ensemble
multiparameter fluorescence detection, EPR spectroscopy,
mutagenesis, and FRET-positioning and screening, and other
biochemical and biophysical tools, we characterize three
short-lived conformational states over the ns-ms timescale.
The use of 33 FRET-derived distance sets, to screen
available T4L structures, reveal that T4L in solution mainly
adopts the known open and closed states in exchange at
4 µs. A newly found minor state, undisclosed by, at
present, more than 500 crystal structures of T4L and sampled
at 230 µs, may be actively involved in the product
release step in catalysis. The presented fluorescence
spectroscopic toolkit will likely accelerate the development
of dynamic structural biology by identifying transient
conformational states that are highly abundant in biology
and critical in enzymatic reactions.},
