摘要

采用化学酶法设计和合成了6′-唾液乳糖修饰的单价和二价纳米体。在大肠杆菌中重组表达了表皮生长因子受体(EGFR)靶向7D12纳米体，包括单价和二价7D12。通过9步合成了甘油三酯修饰的6′-唾液乳糖衍生物。碳水化合物与纳米体的结合是通过Sortase-A介导的高转化率连接实现的。获得的糖工程纳米体最终通过SDS-PAGE、western blot和质谱进行验证。

Chemoenzymatic synthesis of 6′-sialolactose-modified nanobody

6′-Sialolactose-modified mono- and bivalent nanobodies were designed and synthesized by a chemoenzymatic strategy. Epidermal growth factor receptor (EGFR)-targeting 7D12 nanobodies, including mono- and bivalent 7D12, were recombinantly expressed in Escherichia coli. Triglycine-modified 6′-sialolactose derivative was synthesized in nine steps. The conjugation of carbohydrates with nanobodies was achieved by Sortase-A mediated ligation with high conversion rates. The obtained glycoengineered nanobodies were finally verified by SDS-PAGE, western blot, and mass spectrometry.
