FIGURE 3. From: A structural database for k-turn motifs in RNA.

A representative page for one k-turn. This shows a screenshot of the page for Kt-42, with the structure of H. marismortui Kt-42 shown in parallel-eye stereo.

FIGURE 2. From: A structural database for k-turn motifs in RNA.

A map of the k-turn internet site. The front page (top right) presents a review of k-turn structures in RNA. The main functional pages are accessed via the menus at the top left of the web page.

FIGURE 1. From: A structural database for k-turn motifs in RNA.

The k-turn sequence and structure. (A) The secondary structure of a typical k-turn. Nucleotides are numbered according to our nomenclature that can be applied to most k-turns (Liu and Lilley 2007). The 3b•3n position is frequently non-Watson–Crick paired, but the 4b•4n position is usually, but not always, a Watson–Crick base pair. (B) The structure of Kt-7 from the 50S ribosomal subunit of H. marismortui, an archetypal k-turn. The NC (yellow) and C (gray) helices are highlighted by the cylinders, clearly showing the tight angle between the two axes.
