Multivariate Analysis of Conserved Sequence-Structure Relationships in Kinesins: Coupling of the Active Site and a Tubulin-binding Sub-domain

@article{citeulike:1260751, abstract = {An extensive computational analysis of available sequence and crystal structure data was used to identify functionally important residue interactions within the motor domain of the kinesin molecular motor. Principal component analysis revealed that all current kinesin crystal structures reside in one of two main conformations, which differ at the active site, and in the position of a microtubule-binding sub-domain relative to a rigid central core. This sub-domain consists of secondary structure elements [alpha]4-loop12-[alpha]5-loop13 and contains a conserved hydrophilic surface patch that may be involved in strong binding to microtubules. A hinge point for the sub-domain motion lies near a conserved glycine at position 292.
