1i9n Summary



The structure was published by Kim, C.Y., Chandra, P.P., Jain, A., and Christianson, D.W., in 2001 in a paper entitled "Fluoroaromatic-fluoroaromatic interactions between inhibitors bound in the crystal lattice of human carbonic anhydrase II." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.86 Å and deposited in 2001.

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