Usage and Biology

Intein
Intein is a segment of a protein that can self-catalytically excised out and ligate the remaining parts of the protein (N- and C-exteins) with a peptide bond [1].
For this part we used the Npu DnaE intein. This intein is identified as a naturally occurring split mini-intein in Synechocystis sp. PCC6803 [2]. Its first amino acid is cysteine which is important for protein trans-splicing to take place.

This part we used in the сomposite system - N-terminal fragment of β-lactamase fused with dCas13a and N-terminal intein (BBa_K4088891).
