PDB entry 1e12

HALORHODOPSIN, A LIGHT-DRIVEN CHLORIDE PUMP

The structure was published by Kolbe, M., Besir, H., Essen, L.-O., and Oesterhelt, D., in 2000 in a paper entitled "Structure of Light-Driven Chloride Pump Halorhodopsin at 1.8 A Resolution" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2000.

The experimental data on which the structure is based is currently on hold.

The PDB entry contains the structure of HALORHODOPSIN. This molecule has the UniProt identifier P16102 (BACH_HALSA). The sample contained 253 residues which is 92% of the natural sequence. Out of 253 residues 237 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 homotrimers.
