X-RAY CRYSTAL STRUCTURE OF COBALT-BOUND F93I/F95M/W97V CARBONIC ANHYDRASE (CAII) VARIANT

The structure was published by Cox, J.D., Hunt, J.A., Compher, K.M., Fierke, C.A., and Christianson, D.W., in 2000 in a paper entitled "Structural influence of hydrophobic core residues on metal binding and specificity in carbonic anhydrase II." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2000.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of CARBONIC ANHYDRASE. 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.
