Crystal structure of human carbonic anhydrase XIII

The structure was published by Di Fiore, A., Monti, S.M., Hilvo, M., et al., Scozzafava, A., Supuran, C.T., and De Simone, G., in 2008 in a paper entitled "Crystal structure of human carbonic anhydrase XIII and its complex with the inhibitor acetazolamide." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.55 Å and deposited in 2008.

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

This PDB entry contains multiple copies of the structure of Carbonic anhydrase 13.

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.
