NMR SOLUTION STRUCTURE OF CALERYTHRIN, AN EF-HAND CALCIUM-BINDING PROTEIN
Overview
The structure of calerythrin, a prokaryotic 20 kDa calcium-binding protein, has been determined by solution NMR spectroscopy. Distance, dihedral, angle, J coupling, secondary chemical shift, residual dipolar coupling and, radius of gyration restraints reveal four EF-hand motifs arranged in a, compact globular structure. A tight turn in the middle of the amino acid, sequence brings the two halves, each comprising a pair of EF-hands, close, together. The structural similarity between calerythrin and the eukaryotic, sarcoplasmic calcium-binding proteins is notable.
