A peptide ranging from residue 229 to 240 of the D1 protein of Photosystem (PS) II was synthesized and lanthanides were used as candidates of calcium. Fluorescence and FTIR spectroscopy were used to test the conformational adaptation after lanthanide additions. Fluorescence spectroscopy showed that

## Abstract Substitution of Yb^3+^ for the Ca^2+^ in bovine Ξ±βlactalbumin affords a derivative that gives rise to several isotropically shifted ^1^H NMR signals in the range 80 to β 35 ppm in D~2~O. Despite the broadness of the isotropically shifted features, cross signals in both NOESY and COSY sp
