Calcium Channel Embedded in Lipid Bilayer (image) DOE/Brookhaven National Laboratory Share Print E-Mail Caption Scientists used X-rays at Brookhaven Lab's National Synchrotron National Light Source to determine the structure of the proton-regulated calcium channel (ribbons) that is shown above embedded in a lipid bilayer (spheres). This system will be the focus of one of the science challenges of the NWChemEx exascale computing project. The members of the project team will use the computational chemistry code they are developing -- called NWChemEx -- to help them understand what mechanisms underlie proton transfer and how to control calcium leakage for improved stress resistance in plants.
