The structure was published by Royant, A., Nollert, P., Edman, K., et al., Landau, E.M., Pebay-Peyroula, E., and Navarro, J., in 2001 in a paper entitled "X-Ray Structure of Sensory Rhodopsin II at 2.1 A Resolution" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2001.

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

The PDB entry contains the structure of SENSORY RHODOPSIN II. This molecule has the UniProt identifier P42196 (BACS2_NATPH). The sample contained 239 residues which is 100% of the natural sequence. Out of 239 residues 215 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 is most likely monomeric.
