split intein Cfa C

This part is the C-terminal fragment of Cfa. Cfa is a consensus sequence from an alignment of 73 naturally occurring DnaE inteins that are predicted to have fast splicing rates. Cfa demonstrates both rapid protein splicing and unprecedented thermal and chaotropic durability. The 122-124 residues of Cfa is mutated from EKD to GEP, which has been proved to imbue ultrafast DnaE split inteins with minimal extein dependence, thus improving split Intein-mediated protein cyclization. Cfa’C is used in our amplifier to accomplish some complex logic functions. It can also be used by other iGEM teams to assembly their intein-based protein libraries.
