Pinto, F., Thornton, E. L. & Wang, B. An expanded library of orthogonal split inteins enables modular multi-peptide assemblies. Nat. Commun. 11, 1529 (2020).

In this publication, Pinto and colleagues design split sites and characterize a lirary of 34 inteins, 15 of which are sufficiently orthogonal for trans-splicing. The authors have also used these to implement three simultaneous AND gates by splitting ECF sigma-factors. The inteins can also be used to assemble large and repetitive molecules, as shown with spider silk proteins.
