NMR solution structure of calerythrin, an EF-hand calcium-binding protein from Saccharopolyspora erythraea Eur.J.Biochem., 270:2505-2512, 2003 Cited by PubMed Abstract: 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.
