Multidisziplinäre Methoden zur Bestimmung der Kristallstruktur der D‐Ribose – Parallelen zur Ermittlung von Proteinstrukturen

Wolfram Saenger

Abstract: -H ist durch H ersetzt) die Bausteine der 2'-Desoxyribonucleinsäure (DNA).Ein wesentliches Merkmal der b-Furanose in Ribosen oder in 2'-Desoxyribosen der Nucleinsäuren ist, dass der fünfgliedrige Ring nicht planar sondern gewellt vorliegt, entweder in C2'-endo-oder in C3'-endo-Envelope-Konformation, und die Umwandlung zwischen den beiden Formen auf einer Pseudorotation beruht.[2] Die Energiebarriere für die Umwandlung ist so klein, dass die beiden Konformationen in Lösung in einem Gleichgewicht koexistieren, i… Show more

“…NMR studies have shown that ribose in solution is a mixture of α-and β-pyranose and α-and β-furanose forms, the β-pyranose form being predominant. The recently settled crystal structures have shown that the α-and β-pyranose forms are present in the solid phase [239][240][241][242][243]. The structure in the gas phase has been experimentally investigated using a laser ablation molecular beam Fourier transform microwave spectroscopy (LA-MBFTMW) technique [62].…”
