Carp parvalbumin has two calcium-binding domains with a similar three-dimensional structure. Using the tryptic hydrolysis at the arginine residue in position 75, it was possible to split off one calcium-binding domain. All lysine residues were protected by maleic groups which were removed at the final stage. The domain (with a peptide thirty-three residues) isolated by ion-exchange chromatography and gel filtration does not have a secondary structure in a solution and is unable to bind calcium.
