Crystal Structure Analysis of HCA II Mutant T199P in Complex with Bicarbonate

The structure was published by Huang, S., Sjoblom, B., Sauer-Eriksson, A.E., and Jonsson, B.H., in 2002 in a paper entitled "Organization of an efficient carbonic anhydrase: implications for the mechanism based on structure-function studies of a T199P/C206S mutant." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2002.

The experimental data on which the structure is based was not 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 257 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.
