The structure of the A2b and A2n nucleotides in the T. solenopsae Kt-23 and comparison with 2b•2n pairs observed in other k-turns. (A) T. solenopsae Kt-23. The electron density is taken from the composite omit map. (B) The SAM-I riboswitch G2nA k-turn (2YGH). (C) The SAM-I riboswitch k-turn (3GX5). (D) H. marismortui Kt-7 (1FFK).
