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

Int J Pept Protein Res

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

Abstract

  • 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 coordination distance of 2.26A. Both the molecules coordinating to the calcium ion have three fold symmetry, but show significant conformational differences. In one of the peptides of the sandwich, the alternate carbonyls point to the opposite sides of the peptide ring while in the other, all the six carbonyls point to the same side of the ring. Three NH ... O hydrogen bonds between the peptides add to the stability of the sandwich.

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

Abstract

  • 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 carbonyl oxygens, O1 and O4. The molecules exist as dimers in the crystal lattice. The two molecules of the dimer are related by crystallographic twofold symmetry and are linked by two N-H ... O hydrogen bonds. The crystals are trigonal, space group P3(2)12 with a = 11.379(3), c = 32.93(1) and z = 6. The structure was solved by multisolution methods and refined by least squares technique to an R of 0.083.

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

Abstract

  • 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 in solution are consistent with previously proposed solution conformations and permit the identification of spectral lines characteristic of proline-containing peptide bonds in the trans and the cis conformations. Upon cation complexation the prolyl carbonyl stretch bands sharpen and upshift 20-30 cm-1 (to 1690-1700 cm-1). The glycyl carbonyl stretch band is unaffected by Na+ complexation, upshifted approximately 15 cm-1 by K+ complexation, and downshifted approximately 20 cm-1 (to 1619 cm-1) by Ca2+ complexation. Arguments supporting the involvement of prolyl carbonyl groups in cation complexation are noted. Spectra of the Na+ complex of the tetramer cyclo(L-prolylglycyl)4 suggest an asymmetric structure.

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

Abstract

  • 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 A3, Z = 6, M(r) = 527.53, Dc = 1.23 g/cm3. The crystal structure was solved by direct methods using the program SHELXS-86 and refined to an R value of 5.3% for 1645 reflections (I > 2 sigma I). There are two conformers in the crystal structure. One conformer has three carbonyls on one side and three on the other side of the peptide plane. The other conformer has all six of the carbonyls on the same side of the peptide plane. Both of these conformers bind independently to a Li ion. Based on the conformers of the Li complex and other reported ion complexes formed by PG3, we propose a model for the transport of ions across the lipid membrane. The features of the model are as follows: (1) PG3 forms a hexameric stack in a lipid bilayer when complexing and transporting metal ions. (2) It undergoes a conformational flipping in order pass the ion along the channel. The energy required for the conformational change involved in the flipping of the PG3 molecule may be provided by the applied potential during ion transport.
