(A) Time-series histograms of the absolute angular displacement in the θ direction per frame (36 ms). (B) Tryptophan fluorescence changes for a group II chaperonin (TKS1-Cpn L265W) in a mixture of ATP, as measured with a stopped-flow spectrofluorometer. (C) Mean square angular displacement (MSD) in the θ direction as a function of time interval in the presence of 0 mM ATP, 2 mM ATP, or 1 mM ATP-AlFx.
