Backbone assignments of mini-RecA intein with short native exteins and an active N-terminal catalytic cysteine. Academic Article uri icon


  • The backbone resonance assignments of an engineered splicing-inactive mini-RecA intein based on triple resonance experiments with [(13)C,(15)N]-labeled protein are reported. The construct contains inactivating mutations specifically designed to retain most catalytic residues, especially those that are potentially metal-coordinating. The assignments are essential for protein structure determination of a precursor with an active N-terminal catalytic cysteine and for investigation of the atomic details of splicing.
