Raman spectra of the cyclic hexapeptide cyclo-(L-prolylglycyl)3 and its Na+, K+, and Ca2+ complexes are reported for the solid state and for samples in solution. Model compounds and N-deuteration were used to aid mode identification. Spectra of the uncomplexed ionophore...

Calcium plays a crucial role in many cellular processes. Its functions are directly dependent on the high specificity for Ca2+ exhibited by the proteins and ion carriers that bind divalent ions. To elucidate the basis for this specificity we have...

The synthetic cyclic hexapeptide (L-prolyl-glycyl)3 forms a 2:1 complex with Ca2+ ion. The cation is sandwiched between the two peptide molecules. The glycyl carbonyls from each of the peptides are octahedrally coordinated to the cation with an average calcium oxygen...
