Crystallographic Structure of Xanthorhodopsin, a Light-Driven Ion Pump with Dual Chromophore

The structure was published by Luecke, H., Schobert, B., Stagno, J., et al., Wang, J.M., Balashov, S.P., and Lanyi, J.K., in 2008 in a paper entitled "Crystallographic structure of xanthorhodopsin, the light-driven proton pump with a dual chromophore." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2008.

The experimental data on which the structure is based was also deposited.
