Intein trans-splicing

Nettet18. jun. 2024 · The second strategy, named intein-mediated trans-splicing, generates full-length protein at post-translational level, which might be more efficient than the RNA trans-splicing approach. [ 15] Intein is a self-catalytic protein splicing element that excises itself and joins the remaining polypeptides (extein) to a functional protein. Nettet1. feb. 2024 · The key process of BAPTS is a protein trans-splicing reaction of Npu DnaE split intein. Npu DnaE spilt intein consists of a 102 a.a. N-terminal split fragment (Int N) and a 36 a.a. C-terminal split fragment (Int C) [16]. Trans-splicing in BAPTS is thermodynamically favored reaction.
