Human Carbonic Anhydrase III:Structural and Kinetic study of Catalysis and Proton Transfer.

The structure was published by Duda, D.M., Tu, C., Fisher, S.Z., et al., Agbandje-McKenna, M., Silverman, D.N., and McKenna, R., in 2005 in a paper entitled "Human Carbonic Anhydrase III: Structural and Kinetic Study of Catalysis and Proton Transfer" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2005.

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

The PDB entry contains the structure of Carbonic anhydrase III. This molecule has the UniProt identifier P07451 (CAH3_HUMAN)search. The sample contained 266 residues which is 100% of the natural sequence. Out of 266 residues 262 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.
