The effect of hydration on the solid‐state conformation and relaxation behavior of the alkaline earth salts of poly (L‐glutamic acid) has been examined. The calcium and strontium salts take the β‐conformation and the magnesium salt takes the α‐form. No hydration‐dependent...
For a better understanding of the interactions between DNA and various acridine dyes, the binding of acridine (Acr) and 10‐methylacridine (MeAcr) to native and heat‐denatured calf‐thymus DNA was studied in the pH range between 4 and 10 by the equilibrium dialysis and spectroscopic methods....
Infrared dichroism measurements of oriented films of poly(dA)·poly(dT) and poly(d(A‐T))·poly(d(A‐T)) have been made under the conditions of low salts content and high humidity for which the geometry is known. The angles which the transition moments make with the helix axis are compared with...
An optimized potential function for base‐stacking interaction is constructed. Stacking energies between the complementary pairs of a dimer are calculated as a function of the rotational angle and separation distance. Using several different sets of atomic charges, the electrostatic component in...
The application of rotating frame spin‐lattice relaxtion to the determination of the intramolecular motions in peptides is discussed, and results are presented on the application of 13C T1p to peptide microdynamics in solution. The effective molecular rotational reorientation times at the amide...
To obtain information on the solvent‐solute interactions in the dinucleoside monophosphates pertaining to the dimeric subunits of RNA and DNA, we have computed the accessibility of a water molecule to the oxygen atoms of the subunits following the method of Lee and Richards (J. Mol. Biol. 55,...
Measurements of fluorescence depolarization on fumarase labeled with the dye pyrene‐butyryl were used to test for previously reported structural changes in this enzymes. These apparent conformation changes were of interest because they seemed to correlate with variation in catalytic activity...
Several cyclic hemopeptides containing L‐azetidine‐2‐carboxylix acid (Aze)—an imino acid homologous with proline but containing one less methylene group in its cyclic side chain—have been prepared. The peptides reported include (Aze)2, cyclo(Aze)3, and cyclo(Aze)6. The synthesis and...
