The determination of the electric dipole moments of some derivatives of tetraphenylethene and tetraphenylbutatriene

Autor: H. F. van Woerden, C. Altona, C. J. F. BÖttcher

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 80:5-10

The experimental determination of the dipole moments of some derivatives of tetraphenylethene and tetraphenylbutatriene is described. The agreement between the experimental and theoretical values is demonstrated.

Component vicinal coupling constants for calculating side-chain conformations in amino acids

Autor: C. Altona, F.A.A.M. Leeuw

Publikováno v: International Journal of Peptide and Protein Research. 20:120-125

The averaged proton-proton torsion angles for the three side-chain rotamers in amino acids are calculated from a statistical analysis of X-ray structures of side-chain fragments. In combination with a generalized Karplus equation the limiting couplin

Publikováno v: Journal of Molecular Biology. 262:349-357

Electrostatic interactions appear to be important in the conformation and dynamics of DNA four-way junctions. Particularly, the Coulomb repulsion between two approaching phosphate groups at the site of strand exchange is commonly supposed to have a n

Hairpin structures in DNA containing arabinofuranosylcytosine. A combination of nuclear magnetic resonance and molecular dynamics

Autor: E. De Vroom, T. M. G. Koning, G. A. Van Der Marel, C. Altona, Robert Kaptein, J. H. Van Boom, Jane M. L. Pieters

Publikováno v: Biochemistry. 29:788-799

Nuclear magnetic resonance (NMR) and model-building studies were carried out on the hairpin form of the octamer d(CGaCTAGCG) (aC = arabinofuranosylcytosine), referred to as the TA compound. The nonexchangeable protons of the TA compound were assigned
