Crystal Structure of Archaerhodopsin-2

The structure was published by Enami, N., Yoshimura, K., Murakami, M., Okumura, H., Ihara, K., and Kouyama, T., in 2006 in a paper entitled "Crystal structures of archaerhodopsin-1 and -2: Common structural motif in archaeal light-driven proton pumps" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2004.

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