    Naturally split DnaE intein from Nostoc punctiforme (Npu) has robust protein trans-splicing activity and high tolerance of sequence variations at the splicing junctions. We determined the solution structure of a single chain variant of NpuDnaE intein by NMR spectroscopy. Based on the NMR structure and the backbone dynamics of the single chain NpuDnaE intein, we designed a functional split variant of the NpuDnaE intein having a short C-terminal half (C-intein) composed of six residues. In vivo and in vitro protein ligation of model proteins by the newly designed split intein were demonstrated.
