| Abstract: | Active RNase glycoprotein from three pieces : The glycoprotein enzyme ribonuclease C, which contains a complex saccharide N‐glycan, was synthesized by sequential native chemical ligation. An optimized ligation and isolation protocol allowed the efficient assembly and refolding of the 124 amino acid enzyme.  |
