Recombinant kinesin motor domain binds to beta-tubulin and decorates microtubules with a B surface lattice.

Abstract

We have expressed the recombinant squid kinesin head domain in Escherichia coli and studied its interaction with microtubules. The head is active as a microtubule-stimulated ATPase and binds to microtubules, but it does not support microtubule gliding by itself. The head binds to both microtubules and depolymerized tubulin. In each case the zero-length… (More)
