STRUCTURE-ASSISTED REDESIGN OF A PROTEIN-ZINC BINDING SITE WITH FEMTOMOLAR AFFINITY

The structure was published by Ippolito, J.A., Baird Jr., T.T., McGee, S.A., Christianson, D.W., and Fierke, C.A., in 1995 in a paper entitled "Structure-assisted redesign of a protein-zinc-binding site with femtomolar affinity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.25 Å and deposited in 1994.

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 255 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.
