Monastrol is a small, cell-permeable molecule that arrests cells in mitosis by specifically inhibiting Eg5, a member of the Kinesin-5 family. We have used steady-state and presteady-state kinetics as well as equilibrium binding approaches to define the mechanistic basis of S-monastrol inhibition of monomeric human Eg5/KSP. In the absence of microtubules(More)
Strict coordination of the two motor domains of kinesin is required for driving the processive movement of organelles along microtubules. Glutamate 164 of the kinesin heavy chain was shown to be critical for kinesin function through in vivo genetics in Drosophila melanogaster. The mutant motor E164K exhibited reduced steady-state ATPase activity and higher(More)
This paper focusses on pratical problems which may also prove to be of theoretical importance, by presenting a method of establishing an exact topometry of the intrahepatic bile ducts. Measurements were made on corrosive casts of the intrahepatic bile ducts from 13 human livers. On the basis of the topometric results presented it is possible to construct an(More)
