From: Different electrostatic forces drive the binding kinetics of SARS-CoV, SARS-CoV-2 and MERS-CoV Envelope proteins with the PDZ2 domain of ZO1

Figure 2

Ionic strength dependence of the binding reaction between SARS-CoV, SARS-CoV-2 and MERS-CoV E peptides versus different concentrations of PDZ2 domain of ZO1. Top and center panel represent stopped-flow kinetic experiments, while bottom panel represents equilibrium binding experiments at different concentrations of NaCl added to the experimental buffer. Lines are the best fit to a linear (left and center panels) and hyperbolic (right panel) equations. R2 values are reported for all the fitting processes.
