Development of a screening system for inteins active in protein splicing based on intein insertion into the LacZα-peptide.

Abstract excerpt

Protein splicing by inteins has found diverse applications in biotechnology, protein chemistry and chemical biology. Inteins display a wide range of efficiencies and rates unpredictable from their amino acid sequences. Here, we identified positions T22S and S35 in the LacZα peptide as intein insertion sites that strictly require protein splicing, in contrast to cleavage side-reactions, to allow for...
