protein splicing


Also found in: Wikipedia.

protein splicing

a post-translational process in which an internal segment, termed the intervening protein sequence (IVPS), of some PROTEINS is removed, before folding into the final configuration. A new PEPTIDE BOND is formed between the sequences that originally flanked the IVPS. It is an AUTOCATALYTIC reaction.
