Abstract
Charge-swapping of key intermolecular ion clusters in the naturally split DnaE intein from Nostoc punctiforme (NpuWT) alters split intein binding affinities and trans-splicing kinetics. This concept was used to engineer the new split intein NpuMUT with low cross-reactivity to NpuWT. This intein pair can be used to catalyze multiple trans-splicing reactions in one pot with kinetically controlled selectivity (see picture).
