Kink turn
Part Description
A common structural motif identified in functioning RNA species is the kink-turn (k-turn). It typically consists of a tandem trans sugar edge-Hoogsteen G followed by a three-nucleotide bulge: pair A bases. The minor grooves are juxtaposed and the axis of duplex RNA is given a strong bend. The conserved adenine nucleobases of the G:A basepairs accept the cross-strand H-bonds that form at the interface. The k-turns are split into two conformational classes, N3 and N1, by alternative acceptors for one of these. The conformation that a specific k-turn adopts is determined by the base pair (3b:3n) that follows the G:A pairings. K-turns typically bind proteins and mediate tertiary contacts in folded RNA species. Members of the L7Ae family of proteins are frequently found to bind k-turns
