NMR structure of the Aquifex aeolicus tmRNA pseudoknot PK1
Overview
The transfer-messenger RNA (tmRNA) pseudoknot PK1 is essential for, bacterial trans-translation, a ribosomal rescue mechanism. We report the, solution structure of PK1 from Aquifex aeolicus, which despite an, unprecedented small number of nucleotides and thus an unprecented compact, size, displays a very high thermal stability. Several unusual structural, features account for these properties and indicate that PK1 belongs to the, class of ribosomal frameshift pseudoknots. This suggests a similarity, between the mechanism of programmed ribosomal frameshifting and, trans-translation.
