Hoogsteen pairs were first observed in nature in transfer RNA molecules (Fig. 5-31). These molecules contain mostly Watson-Crick base pairs but there are also two reversed Hoogsteen pairs. One of them, between U8 and A14, is invariant in all tRNAs studied. Hoogsteen pairing also occurs in four-stranded DNA, which has important biological functions. A G quartet from a DNA tetraplex held together by Hoogsteen base pairs is shown in Fig. 5-8. [Pg.208]

Figure 5-34 (A) Two conformations of a segment of the yeast phenylalanine tRNA gene. The segment shown codes for the 3 end of the tRNA molecule shown in Fig. 5-30, including the T /C loop. (B) Formation of H-DNA (Fig. 5-24) proposed for a sequence in plasmid pGG32. The major element of the structure is the triplex, which is formed from the Watson-Crick duplex ( ) associated with the homopyrimidine loop through Hoogsteen base pairing (o, +). One of the two possible "isomeric" forms is shown. See Mirkin et al.378... Figure 5-34 (A) Two conformations of a segment of the yeast phenylalanine tRNA gene.

Combination AU62 is the Watson-Crick base pair, AUS2 is called reversed Watson-Crick (Fig. 16.10, left). AU32 is the base pair discovered by Hoogsteen, and AU22 is the reversed Hoogsteen base pair (Fig. 16.10, right). [Pg.259]

Fig. 16.16. The U-A-U base triple observed in poly(U) 2poly(A) is composed of a Watson-Crick AU62 and a Hoogsteen base pair AU32. A corresponding C-G-C triple is not observed. It would only be possible if the C of the Hoogsteen base pair were protonated... Fig. 16.16.

The double helix formed by poly(G) poly(C) does not disproportionate. The reason is that it forms an extremely stable Watson-Crick duplex and that the Hoogsteen base pair could only form if poly(C) were protonated (legend to Fig. 16.16). [Pg.268]
