The sugar pucker is defined by the positions of C2′ and C3′ atoms relative to a plane formed by the C1′, O4′, and C4′ atoms. A sugar with the C2′ is above the ... |
The sugar pucker defines the predominant structure adopted upon base pairing interactions (Figure 1). Four conformations are possible: C3'-endo, C2'-endo, O4'- ... |
Sugar ring pucker refers to conformations of rings, particularly 5-membered rings. Contents Envelope and twist conformations in 5-membered rings. |
13 июн. 2017 г. · Here, we describe an approach for determining sugar pucker conformation in RNA excited states through nuclear magnetic resonance measurements of ... |
FIGURE 3.5 Various sugar ring puckering conformations. Those on the left are denoted S (for south); those on the right, N (for north). |
The ribose ring is not aplanar and usually presents C2'-endo (South) or C3'-endo (North) conformation. For the sugar pucker conformation, homonuclear 3JH-H ... |
Sugar conformation, and therefore 3′-OH position, can change due to mispair formation, as well as from changes in the glycosidic torsion angle (19-23). While a ... |
