The aim of this research was to determine the structure of human, beta-parvalbumin (109 amino acids) and to compare it with its paralog and, ortholog proteins. The structure was determined in solution using, multinuclear and multidimensional NMR methods and refined using, substitution of the EF-hand Ca(2+) ion with a paramagnetic lanthanide. The, resulting family of structures had a backbone rmsd of 0.50 A. Comparison, with rat oncomodulin (X-ray, 1.3 A resolution) as well as with human (NMR, backbone rmsd of 0.49 A) and rat (X-ray, 2.0 A resolution) parvalbumins, reveals small but reliable local differences, often but not always related, to amino acid variability. The analysis of these structures has led us to, propose an explanation for the different affinity for Ca(2+) between, alpha- and beta-parvalbumins and between parvalbumins and calmodulins.
