Crystal Structure of the Closed State of Channelrhodopsin
The structure was published by Kato, H.E., Zhang, F., Yizhar, O., et al., Ishitani, R., Deisseroth, K., and Nureki, O., in 2012 in a paper entitled "Crystal structure of the channelrhodopsin light-gated cation channel" (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2011.
The experimental data on which the structure is based was also deposited.
The PDB entry contains the structure of Archaeal-type opsin 1, Archaeal-type opsin 2. This molecule has the UniProt identifier Q93WP2 (Q93WP2_CHLRE). The sample contained 333 residues which is < 90% of the natural sequence. Out of 333 residues 273 were observed and are deposited in the PDB.
It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
The molecule most likely forms homodimers.
