Crystal Structure of the AQP1 water channel

The structure was published by Sui, H., Han, B.G., Lee, J.K., Walian, P., and Jap, B.K., in 2001 in a paper entitled "Structural basis of water-specific transport through the AQP1 water channel." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2001.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of AQUAPORIN 1. This molecule has the UniProt identifier P47865 (AQP1_BOVIN)search. The sample contained 271 residues which is 100% of the natural sequence. Out of 271 residues 249 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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
