The long-term objective of this research is the integration of F_1-ATPase with NEMS to produce useful nanoscale devices. A thermostable F_1-ATPase coding sequence has been isolated, cloned, and engineered for high-level protein expression. Precise positioning, orientation, and spacing of individual F_1-ATPase molecules were achieved on patterned nickel arrays produced using electron beam lithography. An efficient and accurate assay was developed to evaluate the performance of individual F_1-ATPase motors, and confirmed a three-step mechanism of γ subunit rotation during ATP hydrolysis. Further assessment of the biophysical and bioengineering properties of F_1-ATPase currently are being conducted, as well as the construction of a hybrid NEMS device powered by F_1-ATPase. The evolution of this technology will permit the creation of novel classes of nanoscale, hybrid devices.", pages = "179-184(6)", url = "http://www.ingentaconnect.com/content/klu/bmmd/2000/00000002/00000003/00264805" }
