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.
