Notes
- From the abstract
- Long neck linker inserts decrease processivity by a factor of 3
- kinesin with neck linker inserts rapidly release ADP from both heads when binding to a MT, whereas WT kinesin only quickly releases ADP from the head that binds initially
- They use A25 buffer, which is: 25 mM potassium ACES, pH 6.9,2 mM magnesium acetate, 2m ~ potassium EGTA, 0.1 mM potassium EDTA, and 1 mM 2-mercaptoethanol
- supplemented with 25 mM KCl, so total ionic strength is 50-60, still lower than BRB80 (PEM80), but higher than Yildiz et al. BRB12
