Segmental isotopic labeling by asparaginyl endopeptidase-mediated protein ligation
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,...
Chemical ligation of the influenza M2 protein for solid-state NMR characterization of the cytoplasmic domain
Chemical ligation of the influenza M2 protein for solid-state NMR characterization of the cytoplasmic domain
Abstract
Solid-state NMR-based structure determination of membrane proteins and large protein complexes faces the challenge of limited spectral resolution when the proteins are uniformly 13C-labeled. A strategy to meet this challenge is chemical ligation combined with site-specific or segmental labeling. While chemical ligation has been adopted in NMR studies of water-soluble proteins, it has not been demonstrated for membrane proteins. Here we show chemical ligation of the...

Segmental isotopic labeling of a 140 kDa dimeric multi-domain protein CheA from Escherichia coli by expressed protein ligation and protein trans-splicing
Segmental isotopic labeling of a 140 kDa dimeric multi-domain protein CheA from Escherichia coli by expressed protein ligation and protein trans-splicing
Abstract Segmental isotopic labeling is a powerful labeling tool to facilitate NMR studies of larger proteins by not only alleviating the signal overlap problem but also retaining features of uniform isotopic labeling. Although two approaches, expressed protein ligation (EPL) and protein trans-splicing (PTS), have been mainly used for segmental isotopic labeling, there has been no single example in which both approaches have been...
