    Geometrical and Electronic Structure Variability of the Sugar-phosphate Backbone in Nucleic Acids

  • Original language description

    Quantum chemistry was used to describe alpha/gamma energetics and to access Amber force field parm99 and parmbsc0. This was tested on two models systems: SPM consisting of a sugar and methyl group linked through a phosphodiester bond and SPSOM consistingof two deoxyribose residues (without the bases) connected via a phosphodiester bond. A comparison of the ab initio data with the ff99 potential energy surface clearly reveals an incorrect ff99 force-field description in the regions where the gamma torsion is in the trans conformation.

    Geometrická a elektronická strukturní variabilita cukr-fosfátové páteře v nukleových kyselinách.

  • Czech description

    Kvantová chemie byla využita k popisu energetiky alfa/gama a k ohodnocení ambrovských silových polí parm99 a parmbsc0. Byly testovány dva modelové systémy: SPM sestávající se z cukru a methylové skupiny připojené přes fosfodiesterovou vazbu a SPSOM sestávající se z dvou deoxyribóz (bez bází) spojených přes fosfodiesterovou vazbu. Srovnání ab intio dat s potenciální energií silového pole parm99 jasně ukazuje, že parm99 nesprávně popisuje region kde gama torze je v trans konformaci.
