متن کاملATP Synthase: Motoring to the Finish Line
Protonmotive force produced by the electron transport chain is harnessed by the rotary molecular nanomotor ATP synthase to generate ATP. In this issue of Cell, Adachi et al. (2007), in a dazzling display of technical sophistication, now disentangle the coupling between the mechanical force generated by rotation of the ATP synthase subunits and the chemical reactions that occur simultaneously at...
متن کاملNeurite Extension: Starting at the Finish Line
The outgrowth of axons and dendrites from neuronal cell bodies to their appropriate targets is the canonical means of creating new processes. Heiman and Shaham (2009) now show that neuronal processes can also be made by anchoring dendrite tips at their target locations while the cell body pulls away, a process termed retrograde extension.
