We showed the broad utility of salt-dependent protein splicing in cis and trans by demonstrating backbone cyclization, self-cleavage for purification, and … WebbOne of the most dramatic posttranslational mod- ifications is protein splicing, an autocatalytic process in which an interveningpolypeptidesequence,termedanintein,isexcisedfrom a precursor protein with concomitant splicing of the franking sequences, known as exteins.
Webb20 nov. 2016 · Protein trans-splicing catalyzed by split inteins has been used for segmental isotopic labeling of proteins for alleviating the complexity of NMR signals. Whereas inteins spontaneously trigger protein splicing upon protein folding, inteins from … WebbAbstract. Intein-mediated protein splicing is a self-catalytic process in which the intervening intein sequence is removed from a precursor protein and the flanking extein segments are ligated with a native peptide bond.

Webb7 juli 2005 · In cis-splicing, the U1 snRNP base pairs with the 5' splice site, and U2 snRNP base pairs with the branchpoint near the 3' splice site. The intron is excised and the two exons are spliced together. In trans-splicing there is no 5' splice site on the pre-mRNA for U1 snRNP binding. Instead, the 5' splice site is provided by the donor SL snRNP ...
