2cbd Summary



The structure was published by Hakansson, K., Carlsson, M., Svensson, L.A., and Liljas, A., in 1992 in a paper entitled "Structure of native and apo carbonic anhydrase II and structure of some of its anion-ligand complexes." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.67 Å and deposited in 1992.

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 260 residues which is 100% of the natural sequence. Out of 260 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.
