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(More)
DnaE intein from Nostoc punctiforme (Npu) is one of naturally occurring split inteins, which has robust protein splicing activity. Highly efficient trans-splicing activity of NpuDnaE intein could widen various biotechnological applications. However, structural basis of the efficient protein splicing activity is poorly understood. As a first step toward(More)
