The mechanism of intein-mediated protein splicing was first described using an intein from a Pyrococcus species. Inteins are sporadically dispersed amongst the various phyla. Inteins are often encoded by mobile genetic elements that allow them to be horizontally transferred. Inteins naturally lacking the standard amino-terminal nucleophile can still splice by a slightly different mechanism. Understanding the mechanism of protein splicing has allowed scientists to harness inteins for numerous bioorganic chemistry and biotechnology application
