1bnn Summary



The structure was published by Boriack-Sjodin, P.A., Zeitlin, S., Chen, H.H., et al., May, J.A., Dean, T., and Christianson, D.W., in 1998 in a paper entitled "Structural analysis of inhibitor binding to human carbonic anhydrase II." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1998.

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 259 residues which is 100% of the natural sequence. Out of 259 residues 256 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.
