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.
