No Longer Hidden Secrets of Proton Pumping: The Resolution Revolution Enlightens V-ATPases

, 2018
In this issue of Molecular Cell, Roh et al. (2018) present a high-resolution cryo-EM structure of the nanodisc-reconstituted yeast Vo proton channel that provides important new insights into subunit arrangements and the proton translocation pathway in V ...

Anticipating antiport in P-type ATPases

, 2008
Cation-transporting P-type ATPases show a high degree of structural and functional homology. Nevertheless, for many members of this large family, the molecular mechanism of transport is unclear; namely, whether transport is electrogenic or not and if ...

Patient-specific stopping power calibration for proton therapy planning based on single-detector proton radiography. [PDF]

, 2015
A simple robust optimizer has been developed that can produce patient-specific calibration curves to convert x-ray computed tomography (CT) numbers to relative stopping powers (HU-RSPs) for proton therapy treatment planning.

In situ analysis of pH gradients in mosquito larvae using non-invasive, self-referencing, pH-sensitive microelectrodes

, 2001
The alkaline environment, pH approximately 11, in the anterior midgut lumen of mosquito larvae is essential for normal nutrition and development. The mechanism of alkalization is, however, unknown.
