An improved fluorescent noncanonical amino acid for measuring conformational distributions using time-resolved transition metal ion FRET.

Abstract excerpt

With the recent explosion in high-resolution protein structures, one of the next frontiers in biology is elucidating the mechanisms by which conformational rearrangements in proteins are regulated to meet the needs of cells under changing conditions. Rigorously measuring protein energetics and dynamics requires the development of new methods that can resolve structural heterogeneity and conformational...
