Identifying the mechanisms of intron gain: progress and trends

WebThe intron is inserted within the highly conserved ‘530 loop’, at a site corresponding to positions 531–532 of the E. coli 16rRNA. Residues surrounding the insertion site almost certainly play an important role in ribosomal proofreading function as they proved to be protected by tRNAs in E. coli 16S rRNA (Moazed and Noller 1986; Stern et al. 1986). WebApr 1, 2015 · A twintron is an intron arrangement in which one group II intron is nested inside another intron as a consequence of an intron insertion event (Figure 3L). For a twintron to splice properly, often the inner intron must be spliced out before the outer intron RNA can fold properly and splice [118,120,121].
