The inherent ability of the synthetic L6-7 loop peptide to bind Ca2+ was demonstrated with murexide and mass spectrometry. NMR analysis indicated the formation of specific 1:1 cation complexes of the peptide with calcium and lanthanum with coordination by all three aspartate residues D813/D815/D818 that resulted in an altered conformation of the peptide chain. Overall our observations suggest that, in addition to mediating contact between the intramembranous Ca2+ binding sites and the cytosotic phospho lation site as previously suggested, the L6-7 loop, in a preceding step, participates in the formation of an entrance port important for lodging Ca2+ at a high-affinity binding site inside the membrane.}, Publisher= {NEW YORK ACAD SCIENCES}, Address= {2 EAST 63RD ST, NEW YORK, NY 10021 USA}, Type= {Article; Proceedings Paper}, Language= {English}, Affiliation= {Le Maire, M (Reprint Author), CEA Saclay, Biophys Sect, Dept Biol Joliot Curie, Bat 528, F-91191 Gif Sur Yvette, France.
