  • Title: A molecular orbital investigation of the conformation of transfer RNA.
    Author: Perahia D, Pullman B, Vasilescu D, Cornillon R, Broch H.
    Journal: Biochim Biophys Acta; 1977 Sep 20; 478(2):244-59. PubMed ID: 901794.
    Abstract:
    The PCILO method has been used for a theoretical exploration of the conformational properties of tRNAPhe with respect to the phosphodiester torsion angles. The computations were based on the utilisation of the dinucleoside triphosphate model and took into account the different combinations of sugar puckers and different conformations about the C4'-C5' bond. The dependence of the (omega'-omega) conformational energy maps upon these factors was specified. A detailed comparison is carried out between the theoretical results and experimental data on the crystal structure of tRNAPhe produced by four different groups of investigators.
