(A) The domain structure of the kinesin dimer. Kinesin residues including the head, neck, and a portion of the coiled-coil regions were expressed in bacteria and purified. (B) Coomasie-stained gels of the wild-type and mutant kinesins used in our assays. As assessed by gel filtration chromatography, these proteins eluted as soluble dimers.
