Abstract

Inteins are self-splicing elements that orchestrate the autocatalytic process of protein splicing, during which the intein excises itself from a host polypeptide. This multistep reaction involves a series of coordinated nucleophilic attacks and peptide bond rearrangements that remove the intein and reassemble the flanking halves, called exteins, to form the mature host protein. Some inteins are also mobile elements, and can spread to the same or ectopic sites using an internal homing endonuclease domain.
