Protein splicing is a natural posttranslational editing process where inteins excise themselves and ligate exteins. This mechanism is engineered for protein purification, ligation, and cyclization.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Protein Engineering

Context:

  • Protein splicing is a posttranslational modification.
  • Inteins mediate self-excision and extein ligation.
  • Requires only four intramolecular reactions, no cofactors.

Purpose:

  • To summarize recent advances in protein splicing mechanisms.
  • To highlight applications in protein engineering.
  • To discuss engineering inteins for novel functions.

Summary:

  • Inteins catalyze their own removal from precursor proteins, ligating flanking exteins.
  • Key catalytic residues identified enable protein engineering applications.
  • Inteins facilitate recombinant protein purification and chemical ligation.

Impact:

  • Protein splicing is a versatile tool for protein and peptide manipulation.
  • Enables novel strategies for protein purification and ligation.
  • Facilitates protein cyclization through engineered split inteins.
