The NMR structure of the engineered halophilic DnaE intein for segmental isotopic labeling using conditional protein splicing
Protein trans-splicing catalyzed by split inteins has been used for segmental isotopic labeling of proteins for alleviating the complexity of NMR signals. Whereas inteins spontaneously trigger protein splicing upon protein folding, inteins from extremely halophilic organisms require a high salinity condition to induce protein splicing. We designed and created a salt-inducible intein from the widely used DnaE intein from Nostoc punctiforme by introducing 29...

Segmental isotopic labeling by asparaginyl endopeptidase-mediated protein ligation
Abstract
Segmental isotopic labeling can facilitate NMR studies of large proteins, multi-domain proteins, and proteins with repetitive sequences by alleviating NMR signal overlaps. Segmental isotopic labeling also allows us to investigate an individual domain in the context of a full-length protein by NMR. Several established methods are available for segmental isotopic labeling such as intein-mediated ligation, but each has specific requirements and limitations. Here,...
