Abstract:Finally, we used a single molecule fluorescence quenching assay to study the timing of the neck linker conformational change that occurs as kinesin walks processively along a microtubule. We observed repetitive, alternating cycles of fluorescence and quenching as individual kinesin motors walked along microtubules. By monitoring the position of the kinesin during these fluorescence cycles, we were able to conclude that one cycle of quenching/unquenching occurs with each 8 nm step, and that each step corresponds to an ATP-induced separation of neck linkers.
