Carbonic anhydrase II in complex with a membrane-impermeant sulfonamide inhibitor

The structure was published by Menchise, V., De Simone, G., Alterio, V., et al., Pedone, C., Scozzafava, A., and Supuran, C.T., in 2005 in a paper entitled "Carbonic anhydrase inhibitors: stacking with Phe131 determines active site binding region of inhibitors as exemplified by the X-ray crystal structure of a membrane-impermeant antitumor sulfonamide complexed with isozyme II" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 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 II. This molecule has the UniProt identifier P00918 (CAH2_HUMAN)search. The sample contained 259 residues which is 100% of the natural sequence. Out of 259 residues 258 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.
