On the ion selectivity in Ca-binding proteins: the cyclo(-L-Pro-Gly-)3 peptide as a model.

Proc. Natl. Acad. Sci. U. S. A. 86 , 7880, (1989)

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 calculated t...

Calcium binding cyclic hexapeptide. Crystal structure of cyclo-(L-prolyl-glycyl)3 calcium complex.

Int. J. Pept. Protein Res. 27(2) , 118-22, (1986)

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 calciu...

Crystal and molecular structure of cyclo(L-prolyl-glycyl)3. A cyclic hexapeptide with a cis peptide bond.

Int. J. Pept. Protein Res. 27(2) , 112-7, (1986)

The crystal structure of cyclo(L-Pro-Gly)3 was solved using X-ray crystallographic techniques. The backbone of the peptide is asymmetric and is made up of five trans peptide units and one cis peptide. There is a hydrogen bonded water bridge that links the car...

Cyclo(L-prolylglycyl)3 and its sodium, potassium, and calcium ion complexes: a Raman spectroscopic study.

Biochemistry 19(9) , 1805-13, (1980)

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 uncomplexe...

Crystal structure of cyclo(Pro-Gly)3:Li complex: a model for ion transport by cyclo(Pro-Gly)3.

Biopolymers 34(8) , 1007-13, (1994)

The crystal structure of cyclo(Pro-Gly)3 (PG3) complex with LiSCN (C22H30N7O6SLi) has been solved by x-ray diffraction. The crystals belong to the space group R3 in the hexagonal setting with unit cell parameters of a = 12.581(1), c = 29.705(3) A, V = 4072.0 ...
