Summary
| Description |
English: Base triads in a DNA triple helix structure. In each triad the base shown on the top left forms Hoogsteen hydrogen bonds with the base in the middle. The triads are grouped according to whether they form a triplex of the form YR*Y or YR*R ((Y is a pyrimidine, R is a purine, * is a Hoogsteen pairing). The arrow diagrams on the right indicate the direction and types of the strands forming YR*Y and YR*R triplexes : thick vertical lines, Watson-Crick base pairs; dashed vertical lines, Hoogsteen hydrogen base pairs; solid arrows, purine strands; dashed arrows, pyrimidine strands.
ERROR: TAT AND TAA are labelled wrong/backwards. Figure based on Frank-Kamenetskii and Mirkin (1995) Ann. Rev of Biochem. 64:65-95, drawn with ChemBioDraw Ultra.Türkçe: DNA üçlü sarmal yapısında baz üçlüleri. Her üçlüde, yukarı solda gösterilen baz, ortadaki baz ile Hoogsteen hidrojen bağları oluşturmaktadır. Üçlüler, YR*Y veya YR*R tipi olduklarına göre gruplandırılmıştır (Y bir pürin, R bir pirimidin, * Hogsteen bağlanmasıdır). Sağdaki oklu şekiller, YR*Y ve YR*R tipi üçlülerde iplikçiklerin yönü ve tipini belirtir: kalın dikey çizgiler, Watson-Crick hidrojen baz çiftleri, kesikli dikey çizgiler Hoogsteen baz çiftleri, düz oklar pürin iplikçikleri, kesikli oklar pirimidin iplikçikleri.
