1if9 Summary


Carbonic Anhydrase II Complexed With N-[2-(1H-Indol-5-yl)-butyl]-4-sulfamoyl-benzamide

The structure was published by Grzybowski, B.A., Ishchenko, A.V., Kim, C.Y., et al., Christianson, D.W., Whitesides, G.M., and Shakhnovich, E.I., in 2002 in a paper entitled "Combinatorial computational method gives new picomolar ligands for a known enzyme." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 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.
