Carbonic Anhydrase II mutant W5C-H64C with opened disulfide bond

A publication describing this structure is not available. The depositing authors are Schulze Wischeler, J.search; Heine, A.search; Klebe, G.search

This crystal structure was determined using X-ray diffraction at a resolution of 1.69 Å and deposited in 2010.

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

The PDB entry contains the structure of Carbonic anhydrase 2. This molecule has the UniProt identifier P00918 (CAH2_HUMAN)search. The sample contained 265 residues which is 100% of the natural sequence. Out of 265 residues 254 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.
