Identification of a Novel Non-Catalytic Bicarbonate Binding Site in Eubacterial beta-Carbonic Anhydrase

The structure was published by Cronk, J.D., Rowlett, R.S., Zhang, K.Y.J., et al., Lee, J., Gareiss, P.C., and Preiss, J.R., in 2006 in a paper entitled "Identification of a Novel Noncatalytic Bicarbonate Binding Site in Eubacterial beta-Carbonic Anhydrase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.25 Å and deposited in 2005.

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

This PDB entry contains multiple copies of the structure of Carbonic anhydrase 2.

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 most likely forms homotetramers.
