intein-mediated protein splicing

id: GO:0016539
name: intein-mediated protein splicing
namespace: biological_process
type: go
obsolete: False

Description: The removal of an internal amino acid sequence (an intein) from a protein during protein maturation; the excision of inteins is precise and the N- and C-terminal exteins are joined by a normal peptide bond. Protein splicing involves 4 nucleophilic displacements by the 3 conserved splice junction residues.
