Without hinderance from groups on either ring the adenine ring can rotate about the glycosidic bond, and form the syn conformation. The two common purines, ... |
The syn conformation affords a more compact form of the nucleotide, although it tends to be somewhat higher in energy and therefore more rare. Indeed, ... |
The syn conformation is significantly more energetically accessible with guanine than with adenine in 5-nucleotides but not in nucleosides. Analysis of nucleic ... |
There is only one known case where a purine adopts a syn conformation. The unusual form is to find in an even more unusual structure namely left handed Z-DNA. |
The bond joining the 1'-carbon of the deoxyribose sugar to the heterocyclic base is the N-glycosidic bond. Rotation about this bond gives rise to syn and anti ... 2'-Deoxyribonucleic acid (DNA) · Nucleic acid duplexes |
Generally an anti-conformation can be converted in to a stable syn-conformation by inserting a large substituent at position 6 of the pyrimidine ring or ... |
Videolar Guanosine residues are colored according to the configuration of the glycosidic bond; a nti and syn guanosines are colored aqua and red, respectively. A single ... |
Insertion of the correct nucleotide might be facilitated by the syn-conformation of 1,N2-εdG, which would allow Hoogsteen pairing with incoming dCTP. |
