Angewandte Chemie, EarlyView.Tandem protein trans‐splicing (PTS) assembles a protein from three segments. Expanding this technology to individually treat cysteines in each segment, for example, for chemical labeling using thiol bioconjugation, the authors identify a second, highly efficient cysteine‐less split intein.
