Because KD2 is 1 order of magnitude tighter than nonspecific binding, the second binding event is a distinct and unique molecular interaction.
Thus, unravelling functional TF-gene binding events is a fundamental start-up for us to understand the regulatory mechanisms in cells [ 1].
This result is consistent with the hypothesis that when a transcription factor binding event is conserved, this conservation is a good indictor of a functional regulatory connection [23].
For example, a molecular binding event is represented with an AND gate because both binding partners are necessary to form the bound species.
Rather, the binding event is expected to be a dynamic process involving intermediates before the multiple GBP-glycan receptor interaction partners are established.
As poly-dT is titrated in a solution of SSB (0.125 μM tetramer) in low salt conditions an initial binding event is apparent followed by a second binding event at higher poly-dT concentrations (Fig. 4C).
This shift in the angle is tracked by monitoring the movement of intensity minima of the reflected light with time using the Kretschmann configuration, and the binding event is presented as a sensorgram [ 1].
With crRNA guide in the dCas9 complex, the majority of single-molecule trajectories (66%, n = 60/91) reach a stable high-FRET state (~ 0.95) which, in traces where the initial binding event is observed, transition through a transient intermediate FRET conformation (~ 0.5, arrow) with an average dwell time of 310 ± 40 ms (n = 30, Fig. 4b, top left).
This binding event is characterized mainly by a change (increase) in mass that cannot be solely explained from the peptide weight itself (as it could not lead to such large spectral change, considering its small mass) but could arise from an efflux of the lipid from the plateau Gibbs border into the membrane.
The number of tags expected to map to a binding event is not only dependent on the binding level at a particular site, but also the composition of the total binding event population that is being sampled.
