solution structure of calcium-bound CPV3

The structure was published by Henzl, M.T., Tanner, J.J., and Tan, A., in 2011 in a paper entitled "Solution structures of chicken parvalbumin 3 in the Ca(2+)-free and Ca(2+)-bound states." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2010.

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

The PDB entry contains the structure of Parvalbumin, thymic CPV3. This molecule has the UniProt identifier P43305 (PRVU_CHICK)search. The sample contained 108 residues which is 99% of the natural sequence. Out of 108 residues 108 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.
